Backing Away from Students

Teaching humans anything is a frustrating task. Most people are infested with Dunning-Kruger Effect symptoms and are incapable of absorbing information on subjects that they have convinced themselves they are natural experts. By "most," I mean well over the average 50% of mediocrity. Unfortunately, that group are naturally inclined to be in a position where they need all of the educational help on the planet just to survive. They are ones most likely to be in a classroom and most likely to be unteachable.

I experienced a big contrast in local musicians a few weeks ago. It reminded me of why I have developed an “I don’t give a shit” attitude toward most musicians and their music; especially live. At one end has been working on a half-dozen recordings with Leonard McCracken. One of the best things about moving to Red Wing has been my friendship with Leonard. He is an incredibly generous musician/person and one of the nicest people I have ever known.

A few weeks earlier, after hearing him perform at Marie's Underground and knowing the difference between Leonard’s voice and what comes out of a microphone (SM58) with his traditional rock star technique, I carefully broached Len with the idea that eating the mic is only really useful when there is so much noise on stage that you’re just trying to get some damn vocal in the mic over the din of drums and stage bullshit. Playing solo, there is none of that competition and I suggested he could back off a few inches and let the microphone do some of the work. We talked a little about proximity effect and how that distorts the mic’s output (and emphasizes plosives and sibilance) so that the best you can hope from an already mediocre tool, the SM58, was a mediocre-to-awful signal that needed lots of assistance from EQ circuits that also introduce distortion, phase shift, and an output that barely resembled the input. Then I held my breath, realizing that I’d overstepped a few boundaries and probably pissed him off.

He ate it up and asked the kind of questions my favorite students often asked when they discovered that microphones are not a simple tool. He’s totally revised his technique and you can understand what he is saying and singing on any system. The following Friday night, I brought an EV RE18 to Marie's for Leonard to use in a gig there. Holy shit, he just sounded magical even on Beatles songs (which I usually hate) and was having a great time using a real microphone on his own system (which is pretty good). Then I went the other way. Leonard took a break and he asked a friend to do a song or two to hold his audience. The RE18 is hard for even a typical country singer to fuck up, although he gave it a shot. For the first time ever, I could hear his lyrics over a PA and discovered that I didn’t dislike his voice as much as I’d thought.

Leonard’s friend, Esther, was sitting next to me and started asking questions about microphones and technique and I explained a little, although her technique is pretty good in the first place. The country guy came back to the table and I complimented him on how good he sounded. He listened in for a bit and started contradicting me with total bullshit myths about microphones and tossed out a lot of terms he clear misunderstands (polarity patterns, frequency response, the tube mic religion, etc) and it turned pissy for a bit. Eventually, he resorted to “good microphones are too expensive,” which I thought was  hilarious coming from a fairly average guitarist who insists on an expensive guitar but even mostly considers himself a vocalist. Funny, but not even a little unusual.

Music stores make their living off of guitar players who think spending money will fix their playing, but who may never realize an acoustic guitar is, for most of us, just providing an simple accompaniment to our voices and songs and stories. Leonard regularly proves that cheap (<$300) guitars are fine. He has a fine collection of cheap Chinese and South Korean electric and acoustic guitars that our local repair guy says "are killing the sales of expensive brands because Leonard's guitars sound so good." Of course, the real story is that Leonard makes them sound good.

The other guy and I are probably not likely to be friends and I can’t say I give a fuck. I am, however,  using the experience to try to fashion this Wirebender blog piece. The experience did remind me that I am mostly done with teaching. It was plenty hard trying to teach anything technical,. controversial, or complicated to 20-somethings, but it’s almost always impossible to teach anything to people who have never studied a single adult subject, are cursed with Dunning-Kruger syndrome, and are OLD. Since Trump, my tolerance for stupid and stubborn has just shriveled to zip and my ideal retirement home looks better every day. Ignorant is a different case. I have no problem with people not knowing much about a subject. There are thousands of subjects that I know nothing about and about which would love to learn more. That is ignorance and there should be no shame in that. Stupidity is a chosen quality, though. Arrogance is even worse.

The cheap microphone argument leaves me pretty cold though. Yeah, I know your favorite rock stars lip-sync into SM58's on SNL and stage and if faking it with a cheap Shure mic is good enough for them it should be good enough for you. (About a decade ago, there was a brief period where Neumann and Sennheiser replaced the SM58's on the SNL stage and that was the ONLY period in that program's history where the music performers didn't sound awful.)

The problem is garbage-in/garbage-out. You can not "fix" the original signal; although you can remove some of the crappier parts and try to hide the deficiencies with EQ and compression. That's not a fix, that's just lipstick on a pig. Transient response, sensitivity, phase and frequency accuracy, off-axis response, and the collection of microphone characteristics that are even harder to quantify but we "know 'em when we hear 'em" are not fixable. If you've tried any of the microphone modeling programs, you (hopefully) have realized that you can not make a Neumann U87 out of an SM58 recording. Ideally, you start with either a well-known microphone of high quality or, even better, with a precision condenser microphone. You can always reduce the quality of a signal, but fixing it is beyond science or software and not even on the same planet as live music.

The question I'm asking is, if a $3,000 guitar will make your mediocre guitar playing sound better, why wouldn't a $500-1,000 microphone do the same for your voice? Trust me, it will do far more than the guitar could ever hope to do.

POSTSCRIPT: I recently watched John Mayer's "Where the Light Is" video. The effort he puts into selecting clothing, a watch, and his guitars vs the thoughtless decision to sing into a CB mic (the Shure SM58) is telling. Obviously, the recording and mix engineers put a lot of work into cleaning up the vocal mess Mayer dripped into their preamp, but his voice still sounds as muffled, sibilant, and distorted as does everyone else who improperly uses an already defective tool.

Recently, I talked a local songwriter into using my RE18, instead of his SM58 for a live recording of a performance that we recorded and will be sold as part of an artist grant project. I had to do almost nothing to the output of the RE18 to make the vocal stand clearly on top of the mix. The artist has commented several times on how great his voice sounded both during the performance and on the recording. He is now deciding on whether he will be replacing his 58 with either an RE15 or RE20, both of which has has owned for years and didn't realize were great live microphones. So, sometimes you win and sometimes you don't.

I think I've said this before, but the reason we all carry 58's is that it's such a standard - that if you show up at a gig with anything else, they will look at you sideways. Having done a lot of jobbing, I can tell you that's a real thing.

But for my solo gigs I don't really have any excuse. Do you recommend any dynamic mics for vocal in live performance? (There is an EV N/D367 dynamic at the store I could get for a song...) What condensers would you recommend? I've run into a few Yamaha mixers lately that have low-power phantom that would not correctly power some condensers, goofy.

Cal, I get that. As a live sound equipment provider I would always have a stash of 57/58 crap for the majority of deaf people who imagine themselves to be musicians. I haven't had to deal with that for decades, so I tend to discount that silliness. For recommendations, even more than picking a guitar I think a microphone is hyper-personal choice. Meaning, what I love may not cut it for you. Here's my list in order of preference:
EV RE20 - always my first choice for anything that needs directionality, proximity control, clear reproduction, and high SPL capability
Sennheiser e965 condenser - the McNally Smith shootout winner
Neumann KMS-105 condenser
EV RE520 - a friend recently bought one and it is amazing
EV RE16 (better yet, an RE18 if you can find one with a whole filter and suspension)
Shure KSM9 dynamic
Sennheiser e945 or e935 condensers (I can't tell 'em apart)

None of those are cheap, but some are pretty reasonable.

The phantom power thing is baffling. How is 48VDC at 14mA hard to do? Yamaha consistently baffles me with their mix of competence and incompetence. Tascam, is at least consistently incompetent.
