My Slantmaster 50 Story

Back in the early 2000s, I was happily working as a college instructor for a music school in St. Paul. I was the school’s Student AES Club faculty advisor and I was having the time of my life working with brilliant, inspiring, energetic young people who were fascinated with all things audio. Back in my early-QSC Audio days, I’d built a pretty cool ABX tester and, later (after I’d left California and the pro audio business), QSC decided to build a much more sophisticated ABX tester and use it to promote the company’s products. That didn’t work out well and the ABX testers were recalled from the company’s sales force and, I’d been told, crushed to bury the evidence that someone at QSC once thought professional audio people gave a crap about audio fidelity and honest listening tests. I’d been that same dumbasss a decade earlier, so they had my sympathy. Because I’m lazy and that wheel had already been built, I’d bothered Pat Quilter often to see if he could find an unwanted ABX test box that hadn’t died in the garbage compactor.

Quilter letter

So, in late 2008 when Pat sent me an email warning me that there was a package coming my way, I thought I knew what would be in it. When it arrived, it seemed almost Amazon-oversized for what I thought would be a 1 rack-space piece. The box was also a lot lighter than I’d expected. I cracked the tape at the top of the box and saw the beige tolex, the leather handle, and the black dust cover and I was confused. I knew Pat was retiring from QSC Audio, so I assumed he’d built a model amp as a memento. When I pulled the amp from the box and saw the Slantmaster backCelestion Century 12” I suspected it was more than an empty box demo. I plugged it in, turned it on, and (like everyone I’ve ever show the amp to) said, “Wow!” There is a cool, brief light show from the backlit front panel as the amp powers up that blows everyone away. I spent the rest of the day playing with the amp, which was more guitar playing than I’d done in the past 20-some years.

https://images.reverb.com/image/upload/s--Yp0LAsA9--/f_auto,t_large/v1571546406/frdbeloncpgmtfp50wns.jpgI brought it to school the next day to show it off to students, employees and instructors, and anyone who was interested. We used it several times in recording sessions over the next couple of weeks. One to-be-unnamed guitar instructor tried to buy it from me, tried to get me to have Pat build one for him, and coveted it so blatantly that I started storing it in the secured record lab area so that it wouldn’t disappear. Over the next year, I used the Slantmaster dozens of times with all sorts of guitars and guitarists and it was universally loved by everyone who heard it. It is kind of sad to admit that the amp has never been used outside of McNally Smith College or my home studio. It has never seen a live gig other than the MSCM’s auditorium stage a couple of times by players who I trusted not to abuse it.

This is what the Quilter Labs website has to say about the Slantmaster 50, “Built to celebrate QSC’s 40th anniversary, the Slantmaster 50 used a linear amplifier to deliver 50 ‘hot watts’ to a simply awesome Celestion ‘Century’ neodymium speaker.

“This was the precursor to Quilter Labs foundation.

“Only one hundred were made and featured a spring reverb! These are very limited, so if you have one you are lucky!”

I have one (#72 of 100) and I am well aware of the fact that I am lucky to do so. I have meant to write something about this amazing gift for nearly 15 years, but a conversation about the Slantmaster in the Facebook “Quilter Musical Equipment Owners Group” about the Slantmaster moved me to finally do the work.

https://media.gettyimages.com/photos/patrick-quilter-of-qsc-started-making-guitar-amplifiers-in-the-1960s-picture-id566045317The day I started work at QSC Audio Products in Costa Mesa in early 1983 was the day Pat took his first vacation in a decade. Pat and his mother had booked a tour of Europe on the Orient Express and he’d entrusted me with overseeing the initial production of the first Series One amp, the 1400, without a single unit having yet passed through production. There were . . . problems, but the QSC team of that day pulled together and by Monday afternoon we were cranking out 1400s at a pretty decent pace. The Series One and Three amps were the breakthrough products that put QSC on the pro equipment map and for the next 9 years I was a product engineer, test engineer, manufacturing engineer, manufacturing engineering manager, and tech services manager: 5 different jobs, with a couple that lapped-over each other a bit, in 9 years. Pat and I became friends, partially because I was the interface between his working hours (noon to whenever in the evening) and everyone else and me (7AM to 5-or-whenever-PM). We shared an interest in audio electronics, psychoacoustics, music, guitars and guitar amplifiers, electric vehicles, science fiction and fantasy, literature, and the people we worked with. I quit QSC and left California, after giving notice almost 3 years earlier that I would be leaving when I graduated from Cal State Long Beach, because I could never see myself breaking even economically in southern California and for personal reasons. Pat and I have continued to communicate through email for the past 30 years. I keep his Xmas letters in the same envelope as the letter that came with the Slantmaster.

It’s A Smaller World Than I Imagined

I am working on finishing up, as it is, our basement office after my friend/contractor Dan Jacobson installed an egress window last weekend. That mostly means, so far, me puzzling together the ceiling tile mess the previous owner/nitwit/contractor made when he chopped up the ceiling to install the forced-air HVAC system the repossessing bank hired him to install. (“Wells Fargo, the dumbest bank on the planet.”) Because I don’t know what I’m doing with most of this job, that means a lot of trips to Menards and Ace for materials and, occasional, tools.

Since I’m spending more than the usual amount of time driving, I’m listening to my random playlist of music that I have stored on USB sticks in the pickup or CRV. I probably don’t have more variety on my playlist than most people, but I do have recordings from a lot of unusual artists. Not only do I have music from well-known artists from the 1930s to today, but I have lots of music that I have been personally associated with either as a musician and/or a recording technician since the mid-1970s. If I’d have known I was going to live this long, I’d have hung on to the stuff I recorded with the Tracers and other kid-bands in the 60s, especially my original songs. Sadly, all of that stuff accidentally ended up in a dump somewhere in Omaha when we moved from that city to L.A. in 1983. Still, I have almost 100 hours of music on my USB stick that I can almost guarantee nobody else in the world is playing at any given moment.

Yesterday after a hardware and grocery store run, the playlist landed on Scott Jarrett’s “Uneventful Lives” and, like everything on “The Gift of Thirst,” it’s a song I know pretty well and like a lot (I like everything on that album.). So, I ended up carrying on with the tune when I went into Aldi’s to buy the “software” for dinner last night. I listen to a lot of music that I usually assume nobody but me knows: stuff I’ve/we’ve written or recorded, music friends have recorded, records that I’ve owned for 30-50 years that was either regional or passed through the popular void unnoticed. Some days, it’s kind of a matter of pride to me that all of this great music is probably only being listened to by me at that particular moment. I mean in the whole world of 8 billion babbling nitwits I’m almost guaranteed to be the only person on the planet listening to a particular song at that moment: 1 in 8 billion, 1/8,000,000,000 or 0.0000000125% of the population are listening to what I’m listening to. I know that isn’t true for Scott’s first record, “Without Rhyme or Reason,” but, like a lot of great music, the two records he made in Hudson, WI didn’t get anywhere near the recognition and appreciation they deserved.

So with “Uneventful Lives” in my head as I left the truck, I walked into Aldi’s singing the random bits of chorus and verses (as usual, I can’t remember any lyrics accurately). About half-way into my shopping trip I was walking toward a woman about my age, pushing a cart in the opposite direction in the same isle. About that time I got to the end of a verse, “So we’ll pirouette away, as the band begins to play. And we’ll drink a toast to husbands and to wives.” And as I passed her she sang, in excellent harmony, “And the sweetness of our uneventful lives.”

Because I am incredibly slow-of-wit, I kept walking and singing to myself, but a big part of me was open-mouth stunned. Nothing like that has ever happened to me. A smarter, quicker guy would have turned around, introduced himself, and asked “Where do you know that song from?” or something equally witty. I did not. In fact, it didn’t occur to me that I should do that until I was loading groceries into the truck. By then, I probably couldn’t have picked her out of a lineup of two people, even if one wasn’t an older woman. So, we’ll likely never know who she is. But . . . damn! It is either one amazingly small world, or Scott’s music landed a lot more places than I knew.

Product Review: Positive Grid Spark Go

Sparkl Go frontAbout a year ago, I reviewed the Positive Grid Spark Mini and didn’t find it worth keeping. There were a lot of things to like about it, but it seemed like a larger-than-necessary package for such a low volume device. I was looking for an electric guitar amp that could be used in small acoustic guitar jam situations, for home practice sessions, and anything beyond that would be gravy. Positive Grid must have read my mind with the Ultra-portable Smart Guitar Amp & Bluetooth® Speaker because it meets all of those requirements and adds a bunch of extras. To be honest and clear, there is nothing in the Go firmware or software that is different from the Mini. The difference is that the Go fits in a pocket of my guitar’s gig bag and does everything the Mini does, maybe better.

I, sadly, didn’t figure this out on my own. I was down enough on the Mini that it wouldn’t have occurred to me to try an even smaller Positive Grid amp. Lucky for me, a much smarter friend brought a Go to my home to show off a couple of weeks ago and I was almost instantly sold. After playing with his for an hour or so, I ordered one from Sweetwater and it arrived a few days later.

Spark Go topThe controls to the Spark Go are incredibly basic. The top of the amp contains the 1/4” guitar input jack, the guitar volume control (the ring around the input jack), a 3/5mm headphone/aux out/Line out 1/8” jack (using this connector disables the Go’s speaker), Music +/- volume buttons (Bluetooth is the Music input), a Preset select switch and LEDs to indicate which preset you’ve selected (4 are available).

Spark Go rightThe right side of the amp hosts the remaining USB3 port, a power switch and power LED, and the Bluetooth indicator. The power switch is a little hard to find in good light and almost impossible to find without good lighting. I’m going to paint a white dot on mine. There is a strap button on the left side of the amp.

Spark Go backThere is a rudimentary guitar tuner bult into the preset/Select button setup. Bluetooth setup is pretty obvious and basic. I love the guitar volume control and, since it is an infinite rotary control, it beeps at you when you’re at max volume. The chassis is wrapped in a removeable black rubber-like sleeve that is easy to grip, but does disguise some of the buttons in poor lighting. The back of the amp is brilliantly covered in an even more rubbery base which nicely couples the amp to a floor or table, restricting the speaker disbursement by half (hemispheric) and providing a theoretical 3dB boost over leaving the amp suspended or even on edge. I like to put the amp at my feet when I’m playing with friends (who are mostly on acoustic guitars) and full-up the amp is pretty much a perfect match, volume-wise, with the other instruments in the room.   

Software screenPositive Grid has been fairly aggressive about firmware updates, including the one I downloaded and installed today (10/15/2023, the 2nd update in the month I’ve owned the amp). Updates are installed through the USB3 port via either Windows or Mac OS. So far, all of the updates have been seamless and none have caused problems (imagine that Microsoft and Apple?). The software, either on Android or iOS, is excellent and easy-to-use (essentially Bias 2). As I demonstrated in the Mini review, is insanely flexible, although you can only load 4 presets at a time you can load a lot more than that through “favorites” on the app while playing. You have 33 different amps and 43 different effects to play with and the effects range from (in this order of signal flow and grouped as described): noise gates, compressors (5) and wah (J.J Legendary), drive and overdrive (14), amplifiers (40), modulation (11) and EQ (2), delay (6), and reverb (9).

Spark Go insides

The part of any amplifier review that matters is “how does it sound?” Obviously, there isn’t a lot of bass from a tiny speaker and a passive radiator, but there is enough to create pleasant, musical guitar tones if you aren’t greedy. I wasn’t impressed with the default sounds, but it didn’t take long for me to come up with 4 that I like a lot and at least a couple dozen in my favorites pile to fall back on for other situations. As a direct-to-recording interface, the latency is close to zero and while I usually need to brighten-up the output (especially distorted amp setups) I’m pretty happy with the Go as my recording electric guitar interface, too. For $120, that is a lot of function for the buck and I’ve really upped my guitar practice time as a result. 

Postscript: This past week I tried using the Go as a guitar interface for recording and online music (Sonobus) and it was terrific. I'd read some complaints that the sound was dull or artificial, but I didn't find that to be true at all. I have a couple of emulation pedals and I think the Go is at least as good and a lot more flexible.

The Deaf Leading the Deaf

Because I’m a slow learner, I went to a local outdoor concert this past weekend. The headliner is a friend and I know a couple other folks who would be playing earlier in the day.Honestly, I felt a bit of an obligation to be part of the audience for their music. I know that a Red Wing, MN audience isn’t typical of pop music audiences with an average age approaching at least 70, but music “fans” of all ages are sadly similarly hearing-impaired. Depending on perspective, I was or wasn’t disappointed with the “music.”

Over the past couple of decades, I have become less inclined to suffer for someone else’s “art,” in the form of painfully loud, distorted, weirdly-mixed live music. This isn’t the first time I’ve written about this, so it might be boring. It struck me, about 3 songs into the set I’d come to see, that live music today is doomed because all ends of the people involved in production and listening are functionally deaf or, worse, don’t care about sound quality at all. My friend is a songwriter and his band is tasteful, talented, and they make an extreme effort to stay out of the vocalist’s way. The soundgoober (the man leaning on the console as if it were a drunk’s crutch) started the show with a severely distorted and loud kick drum and bass guitar blast and took 3 songs to squeeze the vocal a little way into the mix; not enough to understand the lyrics but enough to know there was a vocalist. Worse, it took him 45 minutes of “check, one, check, two” crap to do a musically pointless soundcheck, making the headline show start time 30 minutes late.

As usual, when I described my disappointment to other people who had seen the show, I was the Lone Ranger of Criticism. According to the National Institute on Deafness and Other Communication Disorders, “About 2 percent of adults aged 45 to 54 have disabling hearing loss. The rate increases to 8.5 percent for adults aged 55 to 64. Nearly 25 percent of those aged 65 to 74 and 50 percent of those who are 75 and older have disabling hearing loss.” I, personally, think that is grossly optimistic, based on my own experience with live and recorded music listeners. Back in the 80s, the Audio Engineering Society invited an otolaryngologist organization to test the Society’s convention participants on a voluntary basis. The outcome was the discovery that practically everyone involved in music recording and, especially, live music was functionally deaf. Today, most or much of the audience is equally hearing damaged. It is not even slightly odd to be in a small music venue with a band blasting deafening volume and some of the audience, even so-called critical listening reviewers, shouting “I can’t hear you!” In their arrogant, self-centered manner, they are clearly willing to damage everyone else in the room because they are disabled.

Standard NIOSH OSHACheck out these two charts, one from OSHA that was established during WWII manufacturing, and the other from NIOSH that more accurately reflects what is currently known about hearing loss from environmental “noise” (aka “music”). In some fairly progressive companies, the first numbers on either chart are used to determine when hearing protection is required for workers in those benevolent work environments. Typical amplified pop concerts subject their audiences to noise levels upwards from 115dBC, which means after about 30S of “music” you are experiencing permanent hearing damage. The music better be damned amazing to give away your hearing in exchange.

Ego Noise

This has been a week where two of my blogging interests, motorcycling and blogging, have unfortunately grown together into one large irritation. Last Monday, a parade of nitwit of bikers blubbered past our home at their usual barely-above-a-crawl speed and well-above-a-thunderstorm noise level, proving that there are more than enough reasons to defund the lazy, cowardly couch-potatoes who inhabit our local police and sheriff's departments. If you can’t identify a national, state, and local crime that produces enough noise to drown out a freight train, you are too dumb to be carrying a gun and badge and do not deserve to be wasting public funds pretending to be “law enforcement.” 

A few days later, I went to a downtown outdoor concert and was assaulted by another of the many painful, anti-musical sound systems I’ve suffered in my lifetime. I have an stock of ear plugs in the car, but I shouldn’t have to use them to protect myself in an outdoor concert that drew 75 people max. It took me a few moments to realize that it would only get worse and, as a result, my ears rang all through the next day.

A few days after that, we went to a graduation party for a friend who had been workingm part-time and nights, on her Master’s degree for the last 25 years. Her husband made the event into a “look at me” episode by playing in 3 different bands that were all so loud that nobody could carry on a conversation anywhere in the building. His wife’s celebration was turned into a “I can do stuff too” event for her husband. We all only have a wild hope that she heard, or recognized, at least a few of the many congratulations that were mimed her way.

At the first event, I got into a discussion with a self-admitted deaf guy who argued that the sound system wasn’t as bad as I alleged because he could pick out the three instruments and two voices with some effort. We’re talking about a male and female vocal, acoustic guitar, mandolin, and cajon. If you couldn’t at least make out the existence of those “voices,” the sound would amount to pure cacophony. That is a massively low bar for a sound goober to achieve. At the second event, a musician friend and I decided that an upside to this nonsense is that as long as live sound is this bad, there is no point in wasting a lot of energy on learning lyrics. As Ms. Day said, “Every song is ‘Louie, Louie’ so why bother learning any other song?” Honestly, as long as the vocals were sorta in the general territory of the key, even the melody was obscured by the noise, the dominating mediocre bass and guitars.

A few nights ago, an old friend and his daughter went to a Bastille, Nile Rodgers & CHIC, Duran Duran concert at the Atlanta State Farm Arena. His comment on the show was, "The bands were good. The sound was fairly unintelligible due to extreme loudness. But, I didn't let the sound people steal my joy!" He has been nearly a life-long fan of Rodgers and CHIC and “I didn't let the sound people steal my joy” was the best he could say for his outlay of several hundred dollars for the tickets, the cost of the trip and an overnight stay, and the experience. He also spent a good bit of his life working backstage and FOH with professional sound systems and touring companies. That is how low the bar for live, amplified music has become, at best, we hope the sound system doesn’t ruin the experience for us.

1966 Was A Weird Year

By now it should go without much explanation that I’m not a big Beatles fan. In my decline and fading memory, the one album that I remembered liking was “Revolver.” While pawing around some books about pop music, I stumbled on Robert Rodriguez’s Revolver: How the Beatles Re-Imagined Rock 'n' Roll and checked it out from my library. While I was at it, I checked out “Revolver,” too.

Product Cover for Revolver How the Beatles Re-Imagined Rock 'n' Roll Book Softcover by Hal LeonardFirst, the book was a huge disappointment. Mostly, it’s 250 pages of fanboy gushing over Beatles trivia. Since the book was published in 2013, I’d had irrational hope that we’d be past that and into something more technically interesting. There is a small middle section about the actual creation and recording of the record. Some bits of that are interesting, especially the revisionism of the revisionism and some of the funny stuff about how the memories of a quartet of stoners and the people around them were notoriously unreliable. The “correction” several people added to Geoff Emerick's George Harrison grudge from Here, There and Everywhere: My Life Recording the Music of the Beatles was sort of interesting. Before and after that, I could have used some of the Beatle’s 1966 stimulants to stay awake through the book.

History has a nasty habit of dragging us back to reality. Boomers weirdly remember the late 60’s fondly, which makes me suspect they either weren’t there or they we drugged/drunk into oblivion. The crap that was regularly on the late-60’s charts should embarrass my generation into never-again speaking of our musical opinions. Rodriguez regularly puts up US and British record sales chart and consistently 7-8 of 10 songs on those lists are, thankfully, consigned to the sad history of crap music. WLS’s June 1966 playlist put Tommy James’ “Hanky Panky” at the top, followed by “Paperback Writer/Rain” and “Strangers in the Night.” If you ever want to be humbled, musically, poke your birthday into “Find the #1 Song on the Day You Were Born” and get ready to be disgusted. For me, it's “Woody Wood-Pecker” by Kay Kyser and His Orchestra. Yeah, I know, poetic justice at work.

Has Britain lost its faith? - Full Fact“Revolver” was the record whackjobs liked to smash in the 60s. It came out right after John’s famous opinion on American religion hit the news,  “Christianity will go. It will vanish and shrink. I needn’t argue about that; I know I’m right and I will be proved right. We’re more popular than Jesus now. I don’t know which will go first – rock & roll or Christianity. Jesus was all right, but his disciples were thick and ordinary. It’s them twisting it that ruins it for me.” Later, he claimed he was talking about Christianity in England and he probably was and he was pretty obviously right. The chart at left ends in 2011 and, as of 2021, British religious participation declined another 13.1%. Whatever, that controversy did some serious damage to “Revolver’s” record sales, which is partially why it is mostly a forgotten Beatles record.

Revolver (Beatles album) - WikipediaAfter suffering through the book, I decided to see if any part of my good memories of “Revolver” were valid. The library copy was an analog-to-digital version of the 1966 stereo release. First, John Lennon was notoriously unhappy with his voice and gets some credit for whining about having to actually double-track his vocals,.which inspired EMI engineer Ken Townsend to invent the Automatic Double-Tracking (ADT) device used on practically everything in “Revolver.” After listening to “Revolver,” I’m with John. I was painfully reminded of their Chipmunk voices and the squeaky harmonies. While US engineers like Tom Dowd were knocking stereo recording out of the park in 1966 with records like The Young Rascal’s “What Is the Reason,” the Brits were still panning vocals hard left and instruments hard right (or the reverse or other weird combinations) and managing to get some bass into the recordings, too.

Considering the privative 4-track recording technology Martin and Emerick were cursed to be using on “Revolver” and the inflated egos (and lazy spoiled boy habits) they were dealing with it isn’t a terrible record. Listening to it pretty much demolished any fond memories I had. Compare “Revolver” to one of my favorite records of the day, Lorraine Ellison’s “Stay With Me” and get back to me on how great the Beatles were. As much as I appreciated George Martin, Phil Ramone more than topped anything that came out of England for the next decade with his engineering work on this song. And this is exactly why I resented The Beatles in the 60s because the British crap knocked this kind of music off of the charts for almost a decade.

Placing Bets

The music/audiophile equipment business has been selling snake oil to a gullible portion of the public for at least since Emile Berliner began making 5-inch “gramophone” recordings of chamber orchestras. Connectors and conductors are one of the biggest scams perpetrated on the gullible and wealthy “customers.” Lots of people have spent more energy than I on dispelling the myths and bullshit and I think this paper does it as well as anyone, Mission Engineering’s “Measuring Guitar Cables.” I’ve also spent some energy in my past career and more recent articles on some of this stuff, but I’d old, tired, and more amused than outraged these days. In fact, for the most part I’m now totally on the side of the con artists. The past 40 years of watching the incredibly stupid folks who call the rest of us “libtards” has convinced me that there is nothing unethical about scalping people who want to be scalped.

A few nights ago, I was hanging out with a couple of local musicians and one of them began to explain why his $250 guitar cable was better than a regular cable. He is an electrician, by trade, and I’ve found that those guys are typically strong on the NEC and weak on electrical theory and this guy was no exception. He first started off by tossing out a word, “hysteresis,” that he clearly did not understand as some kind of quality connected to electrical conductors. Then, he went on to try and tag the “skin effect” to how he imagined that his new, grossly over-priced cable could make a passive electric bass guitar sound like one of his active instruments.

Pause here while I explain why I am not rich: I am slow-witted. When people say stuff that either blows me away with insight or astounds me in their stupidity I am equally stumped for an unacceptably long time. Sometimes days will pass before I come up with a relevant question or a snappy comeback. As disappointing as I am in print, I am way slower and dumber in person.

A day later, I realized I could have made some serious money that night. I am not a gambling man (at least not with my money), but this wasn’t a gamble. The next time this comes up in conversation I hope to be ready to bet $1,000 that I can easily setup a test that will prove this dude can’t tell the difference from a $10 Chinese-made cord and his grossly over-priced spread. All it will take is an agreement on what would be “proof” in the test (at least a 75% success rate), a blindfold, a pen and paper, a quiet unbiased witness or two, the two test cables, an instrument (especially a bass), an amplifier, and a dozen cable-swaps and about 15 minutes and I’ll be $1,000 richer.

In case you care, the ONLY things that matter in guitar cables are reliability and shielding quality. Reliability is directly connected to the size and quality of the connectors, the ability of the inner conductors to “slip” inside the outer sheath (either with slippery insulation materials or paper/plastic wrapping), and the care the manufacturer takes in assembly. Most shielding, either braided or double-wrapped, provides 100% shielding and, contrary to your high school football coach’s bullshit, 100% is as good as it gets. Avoid aluminum foil shielding because it will become noisy when it is flexed. Long cables are less reliable and more likely to become noisy. Noise is a relative thing with guitars, though. Since they are unbalanced and high impedance, your pickups are likely to be a bigger noise issue than your cables.

Kick Drums and SM58s

For the first time in a while, I “experienced” a live sound-reinforced show last Friday night. At Red Wing’s Sheldon Theater, to be specific. I’d volunteered to monitor one of the Big Turn Music Festival venue’s gate and had occasional moments to wander the theater to hear the three acts from that evening. I’m sure you wouldn’t be surprised to know I was less-than-impressed with the sound goober’s “work.” In fact, it was about as SNAFU as is typical. The goober clearly believed impressing the audience with how much bass (exclusively kick drume) he could shovel into the mix was more important than attempting a musical demonstration. Nothing new there, but it was particularly depressing with the evening’s first act, Tony Cuchetti’s band, because Tony’s powerful voice did not blend well with a kick drum-dominated mix and the other musicians in his band, including the bass player, suffered the same clueless sonic disaster.

From my perspective, if the sound is obviously “reinforced, “ the sound goober is a screwup. Obviously, there are types of music where the sound has to be reinforced because the input is garbage and must be manipulated to resemble music: DJs, too much of hip hop, most metal, and almost all of the crap that falls into today’s Top 100, for example. But music and musicians only need subtle assistance from the sound goober to carry their music into the cheap seats. Doing more than that is just a sound goober projecting his/her own insecurities, sort of like the Harley Davidson characters trying to disguise their lack of motorcycling skills with the “loud pipes save lives” nonsense.

No 58s

After my Sheldon shift, I took in a couple of the other venues and, Saturday, returned to tour the lot of the bars, stores, and churches that had volunteered to be in the Big Turn. A big part of the problem with several acts I heard over the two days was the chronic poor choice of vocal mics for every kind of singer. Over the past 50 years, I haven’t been shy about voicing my opinion of Shure’s SM58 workhorse. The mic is a brick, almost impossible to damage with all sorts of abuse, but it has limited musical applications. The mic’s bandwidth, proximity problems, self-noise, and polar pattern severely limits the SM58’s practical application; especially on quality voices.

Even more confusing is the fact that most vocalists don’t seem to know or care about the damage this lowfi hammer does to their voices. (If your own tool is an SM58, every voice sounds like a nail?) Why do musicians insist on playing their own instruments through their own amplifiers while appearing to be totally indifferent to the instrument their voice passes through? It’s not like it would be complicated to simply remove the 58 from the stand, clip and all, and replace it with a more suitable mic. If the goober can’t deal with the slight (or major, in the case of a condenser) variation in microphone sensitivity, that will be the least of your problems.

The advantage a serious vocalist would have in knowing how to replace the default poor microphone choice with their own well understood and properly selected replacement would be a night-and-day difference in the performance outcome. You could defuse any objections by telling the goober, “My RE20 (for example) has, essentially, the same sensitivity as your SM58, so you won’t need to change the preamp levels. However, I would like to have the vocal EQ set flat and I have selected my own high pass filter values. Thank you.” Or, in the case of a condenser, telling the goober how much gain to take off of the pre.

You might have to actually walk to the sound board to verify the goober knows how to do those things, but it would be worth a trip. It is always a good bet to assume incompetence when it comes to sound goobers. If you are pleasantly surprised, say so. One of the reasons bottom-of-the-barrel types end up running live shows is that the job is too often thankless. If no one notices a good job, the techs who know what they’re doing end up doing something else and the ones who don’t end up wreaking every show they touch.

Friday night, the one place the 58 did an acceptable job was with the last act’s “vocalist.” He was an atonal screamer whose range began where Tony’s left off. and never approached anything resembling musical. I still couldn’t understand the lyrics, but I wasn’t particularly tempted to put much effort into that task.

Overwhelmed by Talent

 I recently read The Road Home, by Jim Harrison and, during a pause in reading this book, I watched an interview with Pat Metheny. Every once in awhile, everyone is overwhelmed by someone else's Talent. Jim Harrison was the kind of writer that wannabe writers probably should avoid. He was so supremely talented that reading anyone else for attempting to write seems like a pointless exercise.

Pat Metheny, in this interview, described the first time he was around "a real jazz guitarist," (Something that happened to him long after he had recorded albums with Gary Burton and his own groups and had established Pat as a jazz guitarist. To the rest of us, Pat has always been "a real jazz guitarist," but his standards are obviously higher.) At that moment, Pat realized how far he had yet to travel before he considered himself to be the real thing.

I've owned guitars for more than 60 years and even played them off-and-on for that long, but I haven't described myself as "a musician" since the late 60s. I have been around real musicians for much more than 3/4 of my life and I know what they look, sound, and act like. I'm not like them. I'm a music hobbyist, at best. My knowledge of music theory is shallow, my physical abilities and skill are remedial, my willingness to study and practice music is limited, and my natural talent is nearly non-existent. After 2/3 of a century, I have nothing that resembles "a voice" as a musician. I sound like everybody else, at best, and like the worst too often.

Several years ago, I invited a friend, Scott Jarrett, to a local jam session when he was visiting us. Scott is a monster on every instrument I've heard him play and he borrowed a mandolin for that jam session. The group was mostly old guys who either picked up music after retirement or restarted playing at that time and the range of "talent" was pretty narrow. And there was Scott. When we left to find lunch, he commented, "There are three things you need to be a musician: a sense of rhythm, some kind of grip on melody and harmony, and an ability to listen. At the least you need one of those. Those guys don't have any of them." To be honest, most of the time the musical output from our little group could best be called "cacophony." You would have to stretch your imagination to find an artistically redeeming moment in an our of our playing. None of us, except Scott and Brian, would be called "musicians" by any real musician.

Lots of no-talent writers are beating up the "10,000 hours" theory of how you become an expert, but it's pretty clear from reading their "analysis" that becoming an expert writer/author is a long ways out of their grasp. More likely, they aren't even inspired enough to do the work to become expert writers (like me). They just got where they are the old fashioned way: they inherited enough money to work for free or incredibly cheap. Becoming a "musician" is, as Pat described in his interview, a hard road. Most of us just want to be guitar collectors, not musicians.

Tinnitus and Us

Survey’s indicate about 5% of all American adults admit to experiencing tinnitus. I use that qualifier in my first sentence because many people do not admit to having unintentionally damaged their hearing; especially musicians and audio “professionals” (using the term very tightly tied to the monetary definition of “professional”). Using that conservative number, at least 16 million US citizens are hearing tones (and probably voices for a loony percentage of that group) that don’t exist in the acoustic world. There is a financial reason for not admitting to tinnitus for many people in music, so expecting honesty from a group that is incentivized to lie about hearing deficiencies is irrational. For example, a recording engineer who admits his hearing is damaged badly enough that silent moments in a mix are filled with a variety of unrelated tones needs a younger, more physically capable assistant to be useful.

A great description from Dr. Amy Sarow on NPR’s 1A program from a few days ago, “What’s happening for those with tinnitus, the brain is searching for sound. And if you have some degree of hearing loss, which is the case for 80 to 90% of those with tinnitus, the brain says ‘Humm, something isn’t right here.’ And so it starts to increase the spontaneous firing rate of the nerve [intended to receive a specific frequency content] and this hyperactivity creates the perception of sound where there isn’t any.” Something about that “spontaneous firing rate of the nerve” explanation really struck an audible note with me. [pun intended] For years, I used an Automatic Gain Control (AGC) electronic analogy to explain the noises we hear in tinnitus. That wasn’t wrong, but it wasn’t entirely accurate either. And it wasn’t even slightly as elegant as the biological explanation.

One of the problems with that analogy is that it implies that the tinnitus frequency is directly related to the note you are hearing. That isn’t always the case. That spontaneous firing rate is likely to be more of a mechanical value generated by resonances in the nerve than a tone-loss relationship. I used to believe that the tinnitus tones were the frequencies lost by the hearing damage and that is also only sort of true.

Noise level and hearing acuity - Tests and applications - Thot Cursus

More importantly, though, it is absolutely useful to understand that the very narrow spectrum of sounds that a typical hearing test provides (see at left) don’t give you much of a picture of potential damage. For example, you might test in the “normal” range at 1000Hz, but be functionally deaf at 1100Hz. Noise-induced hearing damage can be that specific. That mitigates against the value of a traditional, low-tech audiologist’s office test, but it really makes the new over-the counter programmable hearing aids look like the ideal choice for anyone even moderately technical.

Wirebender Audio Rants

Over the dozen years I taught audio engineering at Musictech College and McNally Smith College of Music, I accumulated a lot of material that might be useful to all sorts of budding audio techs and musicians. This site will include comments and questions about professional audio standards, practices, and equipment. I will add occasional product reviews with as many objective and irrational opinions as possible.
