A Declining Market or Just Laziness?

dave'sAt the suggestion (to put it mildly) of a couple of friends, I finally visited Dave’s Guitar Shop in La Crosse, Wisconsin this past week. Weirdly, this small town near the border of Iowa and just across the Mississippi River from Minnesota is known as a “guitar mecca” to lots of guitar collectors. The store deserves that reputation, if for no other reason than not much else about La Crosse is likely to attract national attention. It’s a perfectly nice small city, but not much different from at least 10,000 other similar sized cities. Dave’s Guitar Shop, however, is quite a bit different from other guitar shops. For starters, there are hundreds of guitars and Dave’s is a premier Taylor and PRS dealer along with several other brands. That, alone, is pretty cool.

The reason it has been suggested that I “need to see” this store is that several of my musical friends think my fascination with my two Composite Acoustics carbon fiber guitars is “sick.” I live in a small Minnesota town with a lot of guitar freaks, many of the rich guys who don’t play much but have substantial guitar collections plus there is a community college here that specializes in teaching Guitar Repair and Construction; wood only, of course. One of my local friends died in late August and I helped his widow find homes for his guitar collection and assorted gear over the past couple of months. Even though three of those instruments were high end guitars, it didn’t occur to me that I should play them to see if I had any interest. Several years ago, he swapped a red Composite Acoustics Cargo for my black sunburst Cargo and that turned out to be his favorite guitar to the end of his life. He, still, thought I should own at least one wood acoustic guitar. I made one a few years ago, but gave it to my grandson.

Mrs. Day and I did not travel to La Crosse solely for the purpose of me looking at guitars. That was just a side-benefit of our trip, which was to look at migrating birds (who have yet to arrive in our area). We’re celebrating her 6th cancer-free year after successful treatment by the Mayo Clinic in 2016 and this trip was part of the celebration. After a 120 mile drive and a 2 hour medical exam, Mrs. Day was ready for a nap. I left her and the cat to relax in the hotel and I slipped off to play with guitars at Dave’s.

To be honest, I am not a motivated buyer; mostly just curious. I’d just read the last hard-copy Taylor in-house magazine and there were lots of “this guitar just spoke to me” comments from their many owners. I wondered if a guitar could speak to me or make me feel anything different than I already feel about my pair of carbon fiber acoustic guitars. Contrary to my friends’ opinion of my instruments, I’m pretty happy with them. They are definitely capable of more than I can do, they play easily and comfortably, are simple to maintain, and I like the way they look. So sue me.

https://s3-media2.fl.yelpcdn.com/bphoto/8j-RBwpuuAw9O3uPhBwcww/o.jpgFirst up, on a Wednesday afternoon, I was not surprised to see that The Gig Store, a live and studio sound equipment place (in the same building) and a drum shop next door to Dave’s, appeared to be closed indefinitely. The retail music business is in rough shape and it is likely to get rougher. Dave’s was open and full of guitars. The entrance is all electric stuff all the time, which was fun but not my reason for being there.

The acoustic guitar area is on the south side of the building, through a short and narrow hallway that could easily be mistaken for a shop area. There must have been 100s of acoustic guitars and I played a couple dozen of them. I was most attracted to the Eastman AC series, with a upper bout sound port and a chamfered edge, Eastman seemed to be at least making some effort to be different than the crowd. Feel-wise, though, all of the acoustic guitars I played had pretty much the same neck, body style and feel, general design, and other than variations on the appearance of the wood they might as well been the same guitar; for my purposes. I really wanted to grab a guitar by the neck and feel that comfortable, natural grip I have with my hot-rodded hand-carved Yamaha V-neck. I had wild hopes that someone would take a chance on doing something inventive with the most important part of any guitar.

Guitar necksBut, nope. Vintage Martins are a slight V-shape, but too slight for me. In fact, I had to move fairly quickly from a typical round guitar neck to a Martin to feel the guitar-neck-contoursdifference it is so slight. Somewhere between a “hard V” and this “medium V” is what I’m looking for. And there was nothing like that in Dave’s great big guitar store. Even the lone carbon fiber brand carried in that store, McPherson, totally wimps out on the neck shape. They don’t even list neck shape options on their custom build page. If I wanted one, I’d have to build it myself, but at this stage in my life I’m not sure I want one bad enough to mess with it.

The music business has undergone some huge changes, mostly for the worse, in the past couple of decades. What has been called “Moneyball-for-Everything” has done a lot of damage, if you’re interested in any sort of variety or creativity. Like every other area of US culture, the guitar is not the hip instrument it once was and the majority of folks buying (and collecting) guitars are old farts. Old farts are not looking for anything new, unusual, or even odd. They want a ‘55 Strat or Tele or a 40’s Martin or a 60’s Gibson and not much else. Companies not in that collector strata are making instruments similar enough to the old standbys that you can’t tell much difference between a 1950 Gibson or Martin and a 2022 Taylor or the rest of the crowd of wannabes. So, I did not find anything that tripped any sort of trigger or even interest in all of those fine instruments.

I did leave that shop wondering how I’d feel when I got home and played my own instruments and the next day I found out. I’m unreasonably satisfied with what I have.

One Story, Two Books

One of my wife’s favorite concepts is “evolutionary convergance”; where the same evolutionary decision is made independently, likely because it is a good idea. The two books are The Birth of Loud: Leo Fender, Les Paul, and the Guitar-Pioneering Rivalry That Shaped Rock ‘N’ Roll by Ian S. Port and Play It Loud: An Epic History of the Style, Sound, and Revolution of the Electric Guitar by by Brad Tolinski and Alan di Perna. Play It Loud is a 2016 publication and The Birth of Loud came out this year. Your take on these two books will depend on your personality. The stories are, essentially, the same.

I read Play It Loud first and am just now finishing up The Birth of Loud. Of the two, Play It Loud is my choice.

There are too many technical flaws in The Birth of Loud and the writing style is too emotional and concentrated on personalities rather than technicalities. Your mileage will, probably, vary. Lines like this are show stoppers for me, “When Leo heard this story [about his pickups failing during a performance], he made sure that if the Esquire’s wiring shorted, the signal would only be diminished, not completely cut.” Wrong. If the wiring is “shorted,” there will be no output, regardless of Leo’s technical “genius.” Birth of Loud is littered with this kind of technical foolishness, to the point that when the author attempts to describe how anything works I have to kick into speed reading mode to get past his mistakes and misunderstandings. Otherwise, I’d toss the book in a pile and find something more interesting to read. There are moments in Birth of Loud that make suffering the flaws worthwhile, though. I knew almost nothing about Paul Bigsby, other than the fact that he knew the difference between vibrato and tremolo; unlike Leo Fender. By himself, he would be an interesting story, so the fact that there is a little more about Bigsby in Birth than Play makes that book worth reading; at least, for me. I do have to suffer through an awful lot of hyperbole, emotional language, and outright silliness to get to the good stuff, though. Port’s descriptions of the music discussed in the book are so over-the-top silly that it’s hard to take any of the book seriously.

Play it Loud is less emotional, more technically accurate, and a more entertaining and interesting read. The authors either check each other’s excesses and technical misunderstandings or they are simple more knowledgeable; or they had a better editor.

Interestingly, neither book is the usual Les Paul pandering that we’ve suffered for the last 40 years. I suppose Paul has been dead “long enough” that the shadow of his self-promotion is fading. I remember watching a Los Angeles AES discussion in the 80’s where Les Paul and Tom Dowd were on the panel and when Les started bragging about buying the “first Ampex 8-track machine,” Dowd reminded him that most of the design work on that machine came from Dowd and Ross Snyder’s idea of making a single 1” multi-track head, instead of Paul’s stacked individual heads and eight stacked ¼” tapes. Also, both Dowd and Paul ordered 8-track machines, more or less, at the same time and Paul’s was supposed to be delivered first, but Dowd snatched it off of the Ampex loading dock and installed it himself. Ampex delivered the 2nd one to Les Paul’s studio and installed it for him. Les Paul was the Jimmy Page of his time, claiming the creation of everything from electric guitar pickups to solid body Spanish-style guitars to recording techniques to tube amplifiers. Of course, there were predecessors for all of those inventions, but Paul made his claims more often, louder, and more prominently than that actual inventors. His contribution to the famous Gibson Les Paul guitars is accurately reduced to his signature on the instruments and some of people who actually designed those instruments are credited. History is catching up to Les Paul’s legacy.

Leo Fender gets a similar look in both books, probably more harshly/realistically in The Birth of Loud. His personal and technical limitations have been rarely discussed outside of knowledgeable conversations between engineers or technicians. The fact that Leo overcame his technical limitations with hard work is a fact, but the fact that his products were littered with the downside of those technical limitations has barely received a mention. The contributions of the many people who compensated for Leo’s limitations are finally documented in both of these books. Rarely, does one person actually “create” a significant product; almost never, in fact. Fender’s guitars and amplifiers are the product of a lot of unheralded effort by many people who at least get acknowledged in both of these books, more so in The Birth of Loud, to the credit of Ian Port.

An Acoustic Guitar Experiment

acoustic guitarOne of many irritants about getting old has been circulation issues. I sleep with at least one half of my body tingling from lack of circulation regardless of which side I sleep on, bed softness or hardness (although, hard is better), sleep position (although after being married for 51 years I am “trained” not to sleep on my back), pills, or anything else I’ve tried. Playing guitar is one more place where my poor technique has turned into a minor medical issue. Like many non-classical guitarists, I “rest” my right arm on the edge of the lower bout. For 50-some years, that hasn’t been a problem for anything but the limitations in speed and technique it causes (which are substantial, I know, Scott). This last couple of years, it has begun to cause another problem. After a few minutes of playing or practice, my wrist, hand, and fingers begin to tingle and will eventually get numb feeling from the lack of circulation caused by that pressure on the edge on the blood vessels of my inner arm.

A few months back, I saw Brian Stewart—music store owner and guitar builder/technician extraordinaire—working on an arm rest for one of his customers. I wondered if that device might help with my circulation problem? So, I built one.

Saturday morning at the TreeStrings morning jam, I tried it out. For the most part, it worked pretty well. Brian and I talked about his design verses mine and we had some other ideas as to how this might become an actual product (which he really doesn’t want to build) and I thought about some of those changes while I played this morning. I wish I’d taken a picture of my original design, if for no other reason than to show the evolution of the idea and because I thought the original piece was really pretty. It did cover more of the top than necessary and was heavier than necessary, too. To keep from having to split another piece of walnut to start from scratch, I decided to hack away at my original piece. Might have been a mistake.  

When I got back home, I took that first attempt down to my basement shop and started carving it down to about half of the original width. I smoothed out the bandsaw cuts, sanded the piece back to a beautiful gunstock satin, and tried it again. This time it wasn’t nearly as comfortable as my original design and that was a huge disappointment. So, I reshaped the top side, losing about 1/3 of the total thickness and creating a little more of a flat spot on top while keeping the soft edge I’d originally designed. I refinished that work and reattached the piece. For the initial experiments, I’m using fairly weak double-sided tape to hold the piece in place, but when I decide I’m happy with it I’ll use something more aggressive.

One of the things I did not expect to happen was for the guitar’s tone and output to change for the better. If you look at that guitar-playing picture (at the top of this essay), you’ll notice that the arm damps a fair portion of the guitar top (especially true when the player is wearing long sleeve anything). I play a very small Composite Acoustics Cargo travel guitar and I’d never really thought much about how much of the guitar’s top I was sacrificing with my playing technique (I know, Scott). After listening the “with and not-with” sound of the guitar, I was interested in the concept on a whole different level. I would guess the overall volume is close to 3dBSPL louder with the arm rest in place and it is substantially more full and brighter, too. In retrospect, all of that makes perfect sense, but I hadn’t thought about it until the evidence was right there in my arms.

I will be playing with this concept a lot more in the future. For now, I’m enjoying being able to practice guitar for several hours without numbness and that irritating feeling (or lack of) that comes with circulation problems.

Updating the CA Story

Way back in 2014, I bought a used Composite Acoutics Cargo travel guitar. I liked it a lot then and I like it more now. Peavey bought the remnants of CA and that company appears to be purging the memory of the original company as quickly as possible. So, I thought I’d try to compile a little history while it’s still possible:

Because?

The explaination that I have disliked the most for 99% of my life is, “Because everyone else does it this way.” An adopted (from Bertrand Russell) mantra of my life has been, “The fact that an opinion has been widely held is no evidence whatever that it is not utterly absurd; indeed in view of the silliness of the majority of mankind, a widespread belief is more often likely to be foolish than sensible." I absolutely believe that statement: regarding subjects from technology to economics to politics to community/religion. I will always assume that “everyone else” is probably a moron, especially if the thing we’re talking about has any aspect of opinion involved. Often, it turns out that I’m wrong. Sometimes the reason people have done something the same way for a long time is that it is the most efficient, practical, easiest, and even effective way to do that thing. Sometimes I’m right and the reason people have been doing something the same way for a 1,000 years is because they are lazy, superstitious, ignorant, timid/conservative, and/or mentally challenged. With only one life to live and a limited amount of time, energy, and patience with which to live it, I am often uninspired to spend much effort worrying about why things “have always beend one this way.” That is not always (or even often) a strength, it’s just a thing, a personality glitch.

IMG_8123So, when it came time to design an electric guitar (a bass, in my case), I decided to blow off a lot of convention and explore my inner designer. Andf I learned a few things: some useful, some I could have spared myself by going with “conventional wiseom,” and some were outright surprises.

For example, I put a lot of thought and effort into creating the smallest body design possible and still retain “balance.” I started with thicker material than I expected to need and installed a 1/2” cap over the wiring routing holes, creating an instrument from which I expected to carve a lot from the back to create a slight “wrap-around” feel. As the body approached completion and the neck was finished enough to attach, I started fooling with finding the point where the strap pins could be installed to make the instrument hang in a neutral, balanced, position. To my mind, that sounded more comfortable than the body-heavy designs of most guitars.

2017-05-01 Bass (3)I was wrong. It turns out that a slight bias toward body-heavy is more comfortable, at least for my playing position. I tend to play with the instrument high and the neck much higher; probably due to short arms or some such handicapped characteristic.

It also turned out that the sculpting I intended to do was unnecessary. My body design conformed so well that additional wood-removal was pointless. It would, however, have been a good exercise. So, I might build another bass using the same general design but taking the body-shaping further.

I also blew off the trait most of my fellow students had for pickup selection. First, it’s a bass and, second, this instrument is one I built purely for my own enjoyment and playing. I’m not a particularly complicated bass player. I don’t solo, ever. I like being part of the rhythm section, in the background, just filling in the bottom. The pickup on my bass has a fairly simple task: provide as much fundamental as possible with as little noise as possible. I went for a Chinese knockoff of a Gibson humbucker design, primarily because the pickup came with individual coil wiring. When I received the pickup, I tested the two coils and found that one had slightly (10%) higher impedance and resistance. So, I unwrapped the coils and pulled wire off of that coil until it was very close to the other coil. I reassembled the pickup, soaking the winding in wax before retaping it, coated the pickup pocket and wiring channels in magnetic paint, and hooked up the pickup for series and parallel operation with a single DPDT switch. Add a volume control and a jack and that’s all I need; along with a mostly-midpoint pickup position. I never use the bridge pickup, so why install one?

You can see that my body shape is unconventional. It works beautifully, by the way. It is comfortable standing or sitting and the “handle” is a lot more useful than a horn.

Proof in Pudding

IMG_0003 July 2014

A while back, I referenced new knowledge (to me) about owning an acoustic guitar that I’d discovered in Allen St. John’s Clapton's Guitar: Watching Wayne Henderson Build the Perfect Instrument. If you look at the picture of me playing my new guitar and if you’ve read St. John’s book, you’d have to assume I learned absolutely nothing from Wayne Henderson. You might be wrong. I’m not a good enough guitarist to know much about the intricacies of acoustic guitars, but like all pedestrian art lovers “I know what I like.” I can’t describe it well enough to put forward any intelligent theories or descriptions, but I am reasonably sure I could put together a list of important criteria that might provide someone with a bigger brain some insight into what matters to me as a guitar player. 

IMG_0004 The guitar I ended up with is a Composite Acoustics Cargo, that company’s entry into the environmentally indelicate travel guitar market. Here’s what CA has to say about the Cargo, “A travel size instrument that sounds like a full size guitar? Impossible! Our Cargo is comfortable to play anywhere, from the forests of Oregon to the foothills of the Catskill mountains, and even in your favorite armchair. Finely appointed and incredibly durable, the Cargo is ready when you are. It easily fits airline overheads or anywhere space is tight. It's a portable guitar with the playability, sound and satisfaction of a full size guitar.

blackbird rider Oddly, other than the exclamation marks, I pretty much agree with CA’s self-assessment. A friend called, knowing that I was looking for a replacement for my all-around-miserable Martin Backpacker travel guitar, saying that he’d found a used Cargo at a local guitar store and wanted to know if I was interested in tagging along to play it with him. We went to Willie’s American Guitars, first, to check out the Blackbird Rider (steel string). The Rider was pretty impressive, but at $1,600 I decided to wait until I’d sold my Martin 00016C before I plunked down another pile off money on a guitar I might not play. On we went to the next guitar shop where we played a used and purple 2008 (pre-Peavey) Cargo non-electric. The shop was asking $1,000 due to the “collector value” of the pre-Peavey status and Tim and I decided to pass for a while to see how the day’s comparisons sat. When I got home, I looked up current prices on the Cargo and found that $999 was a pretty common street price for the electric-capable version of the “raw carbon” version. Tim ended up ordering one from Sweetwater. About the time he ordered his, I found a used one with the “high gloss carbon burst finish” on Craig’s List. We ended up getting our hands on our new guitars at about the same time, same day, and damn near the same place. Tim’s is new, mine is pre-Peavey used. To my ears, they look and sound pretty much the same, except for string differences and the gloss finish on my guitar.

IMG_0003Ellis Seal, an aerospace engineer, began Composite Acoustics in 1999 and after several wrong steps, over-optimistically anticipating the market for the company’s products and under-pricing their products (at least pricing them so the company didn’t make enough profit to survive), CA went bankrupt in 2010. That same year, Peavey bought the remains and began marketing the carbon graphite guitars, pretty much unchanged, in early 2011. Since then, Peavey has refined some manufacturing processes, but kept the guitars themselves most intact; in spite of the fear-mongering some “vintage guitar” dealers are promoting. 

The Cargo is an interesting work in acoustics, psychoacoustics, nearfield design, art, engineering, and ergonomics. After I got my Cargo, Willie’s picked up another Rider and I went to the store with my guitar to compare the two. The Rider has the “advantage” of a smaller body, which makes it slightly easier to store or stuff into airline overhead baggage. That aspect of the Rider turns into a disadvantage when you are playing the guitar. It does not sit comfortably  in your lap like a guitar, unlike the Cargo. While the body of the Rider is more narrow, it is also deeper so the total stored volume is pretty similar. From a distance, the two guitars sound remarkably similar. From the player’s position, the Cargo has it all over the Rider. The sound hole is high and right under the player’s face, providing more low end to that listening position than the Rider. The body shape of the Cargo puts a very resonant part of the guitar’s back right against your chest and rib cage, providing low frequency bone conduction. Just holding the guitar away a fraction of an inch or wearing a coat is enough to lose this portion of the bottom end. It is a brilliant solution to an otherwise unsolvable problem with a small body guitar. Both guitars have excellent pickups; the Rider the Fishman MiSi pickup electronics, with a tone control, and the Cargo has a less-featured but very competent LR Baggs pickup. With a half-decent acoustic guitar amplifier, the Rider’s tone controls would be unnecessary. 

Your mileage may vary, but I am more than satisfied with my Composite Acoustics Cargo electric and expect to be playing this guitar for years. When a friend first saw the CA guitars at a NAMM show, the company had three of their instruments on stands under a running waterfall. The demonstrator just pulled a guitar out of the water, shook it off, and started playing. That’s not all that far from the kind of environment living in an RV can be. 

POSTSCRIPT: A couple of years ago, after moving to Red Wing, a friend decided he also needed a travel guitar. He actually travels, so "needed" was more realistic for him than me. Through an industry connection, he spotted a used CA Cargo for a decent price . . . but it was red. I loved my old black sunburst Cargo, but I kind of don't care about color all that much, so I offered to trade if he really didn't like the red guitar. He didn't, so we traded. 

Since then, I've added a few "features" to the new Cargo (this one is, I think, a Peavey manufactured guitar). The setup wasn't great, so I made a new saddle and dressed the frets a bit. I experimented with an "arm rest" when I was having arthritis issues with my right hand and found that the guitar was substantially louder and more full sounding without my arm resting on the top (Go figure!). For several years, I got to play the black Cargo occasionally and I'm sorry to say I still like it slightly better than the red guitar, but I still kind of don't care much. My friend died recently and his wife sold the Black Cargo to a local musician. It went to a good home. The Cargo is so much my go-to guitar that it lives in the room where I do most of my living, writing, reading, and thinking. After 8 years, it is still my favorite guitar. 

Sad to say, Peavey couldn't figure out how to make and sell the Composite Acoustics line and it has languished on their website with no available inventory or support for at least 4 years.
