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.

The High Cost of Doubt

When I was a working engineer and, later, an engineering manager, my least favorite answer to any question was always, “Because everyone does it that way.” For the last 50 years, a mantra of mine, and my current email signature, has been a Bertrand Russell quote, “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." More than often this is true, but occasionally my kneejerk reaction to convention takes me, the hard way, through the processes that others have already explored and I discover sometimes things are always done pretty much the same way for a reason. Sometimes that reason is bullshit, but there is often a core assumption to be evaluated that with my limited-to-non-existent visual skills I can not see until I experiment.

steinberger-l-series-bass-guitar-2000I am making an electric bass this semester in my Red Wing Southeast Community Tech Guitar Repair and Building program. There are imposed limitations on the kind of instrument we can build as first year students. (I know, I’ve been at it for two years and I’m still taking 1st year classes. Get over it. I am in no hurry.)

My baseline bass is a Steinberg L-Series headless and almost body-less bass. I’ve owned a couple of these instruments in the last thirty years and, currently, own and play a Hohner knock-off of this bass. I love everything about my Hohner from the low weight to the perfect balance to the sound. The only thing I don’t love is the look, which is always a heavily enameled solid color body and neck with a rosewood fingerboard. If the guitar is going to be made from wood, which my Hohner is and my Steinbergers were not. The headless design was not an option for the first year guitar design course. One of the failures from my acoustic guitar build was my original intention to make my instrument from all-domestic wood. I screwed up my first two walnut fingerboards and my one-piece walnut neck block and had to start over quickly, so I snagged a slab of quarter-sawn rosewood and a mahogany neck block from a guitar builder who was dumping material stock cheap and those two critical parts of the instrument ended up coming from imported wood.

This time, I wanted to avoid that and my design was for all walnut; partially because I love the look of walnut and partially because I wanted to take a second look at a design I started almost 40 years ago. That design was based on the B.C. Rich Mockingbird body and incorporated a fretless Fender Precision neck. Considering my rookie woodworking status, that instrument came out pretty well, except that it weighed close to 50 pounds. I started with a 2” thick piece of old growth walnut that I’d milled myself from rough walnut stock I’d found in a friend’s barn. For my current instrument, I wanted everything I’d accomplished with that original instrument without the physical stress. Literally, my bandmates called my old bass “the refrigerator” because between the bass and the Star roadcase, hauling that thing up a flight of stairs was a lot like carrying a refrigerator with one hand. It currently resides in my daughter’s music room where no one has played it for decades. Honestly, it was a terrific bass, sonically, but it will cut a groove in your shoulder that will bisect the player if given enough time.

IMG_8135IMG_8134Once the bass was assembled and finished, I had to decide where to install the strap pins. My working theory was “balanced,” So, I fooled around with clamps, string, and a strap until I found a location that appeared to be evenly balanced. I wrestled with this measurement for quite a while and mentally wrestled with my memory of instrument feel, strap constriction or flexibility (tightly restrained or hyper loose like the classical acoustic guitar strap attachment), and the concept of “balance” for hours. Finally, I decided to blow off convention and attach the strap in the two places shown in these two pictures. Punching holes in my recently sanded, finished, and polished instrument wasn’t an easy move and going for something less convention for the neck position pin was a mental stretch.

IMG_8137

The picture at left shows what balanced looks like. The guitar hangs perfectly neutral when the neck is parallel to the ground. This sort of defeats about 50% of the reason I designed in that “handle” at the top of the instrument, but I thought balance was more important than justifying my design geekiness. Turns out, balanced is not particularly comfortable in a bass, at least for me. While my Steinberger/Hohner L-Series instruments are, in fact, balanced, a slight increase in headstock weight makes a body-heavy strap positon a lot more desireable. For one, I have short limbs (and fingers) and I end up pulling the neck up and slightly to my right when I play the bass. So, I repositioned the neck pin as far up that “handle” as possible, which is pretty much exactly where everyone else on the planet puts a neck strap pin. The end result was a much more comfortable balance and a more relaxed playing position. Which, of course, everyone who has built an electric guitar in the last 75 years knew before I decided to test traditional thinking.

Reflections on Guitar Building

When I started actively looking at moving, I stopped at Southeast Community Technical College to get a feel for the possibilities (for me) in that program if we moved to Red Wing. Luckily, I hit a day when David Vincent was working on course preparation and he spent a couple hours with me showing me the facilities, talking about my experiences at McNally Smith, and my experience with tools, shop equipment, and guitar repairs.

David also described the first year of classes and when he told me about “GTRB 1400 Intro to Tools,” I admit that I balked at having to take a basic hand and power tools class after a lifetime of tool-using. Since I wouldn’t be able to get in to the program for about a year, David recommended that I consider the cabinet-making class in Winona just to get my woodworking skills up a bit. So, I did. That was a pretty awful class, but it did show me how much I didn’t know about power tools I thought I was fairly familiar with.  I really didn’t want to take “Intro to Tools.” David made it clear that skipping that class wasn’t an option.

So, I signed up for all but one of the classes a first year student takes in the fall of 2015. I didn’t take the Electric Guitar Design class my first year because I wasn’t yet convinced I wanted to build an electric guitar. After three weeks of “Intro to Tools” I wasn’t convinced I was going to be building any sort of guitar. David’s class was kicking my ass. It turns out that my personal quality standards weren’t even close to good enough for a luthier.

To start, we all had a list of fairly expensive tools to buy. Four Canadian-made chisels for about $120 for the set, were on the list. You’d think that if you paid that kind of cash for a couple of pounds of steel they would come sharpened by the manufacturer. You’d be wrong. There was also a 4” plane on the list. It cost about $70 and it also needed sharpening. We spent about a week (it felt like a month) learning how to properly sharpen these tools. In the end, I was able to create an edge that would easily shave the hair off of my arm. The factory edge was far from that sort of edge.

IMG_7887For example, this sanding stick. It’s about 10” long, with a prescribed taper, different on both sides, and two different radiused sides, also prescribed by Mr. Vincent. I worked on that stick for days and, after three weeks, didn’t feel I was any closer to getting it right (+/-0.002” for all specified dimensions) than I was when I started. Everyday, for a couple of weeks, I wrestled with myself and my failure to be able to do the work to David’s standards. I was not that far from the edge of saying, “Screw this. I’m retired and I don’t need eight hours a day of failure.” Then, I got it. All of a sudden, I was not only getting the assignments but I was bringing in work from  home and doing it to my new workmanship standards.

2016 SETC Guitar Show (8)In the end, I did pretty well. I made the Dean’s list and, even more importantly, I made this guitar. Yeah, I know it’s a long ways from a Gibson Hummingbird, but it is exactly what I wanted to build, including a fairly individual semi-V shaped neck that I LOVE.

Also, I have a trio of super-sharp planes—from a 6” 1950’s Stanley to a 24” Stanley/Bailey that found in a Red Wing garage sale for $10 (with two new 7” saw blades tossed in for good measure) that I turned into a terrific manual joiner.

Occasionally, in my 68 years, I have learned things that if I’d have had them in hand when I was young would have made a world of difference in my life. This first year at Southeast Community Technical College was full of that kind of experience. I’m not kidding when I say that I think every kid who doesn’t know what he or she wants to post-high school ought to seriously consider the Southeast Tech Guitar Bulding and Repair Program. You will not be the same person after you’ve experienced the high standards this school and these instructors set for you.

How Quality Feedback Really Works

A while back, I was arguing with one of my MNSCU instructors about why he needed to get over his fear of lead-free solder and move his instruction program into this century. During this “discussion,” mentioned that the electrical assembly portion of almost every electric guitar I’ve ever disassembled has been an embarrassment. From the major factories to the boutique builders, the soldering, component placement and security, and wiring have been . . . sad. Likewise, many of the guitars (and other audio products) I’ve repaired in my career have failed because of soldering defects. His response was, “Don’t you think one of my long term customers would have complained if my soldering failed?”

My short answer was, “No.”

This isn’t the first time I’ve written about this discussion, but it keeps coming back to haunt me. There is an old 5/5/5 restaurant rule that says something like “It takes $5 in advertising to get a new customer to try a business, 5 seconds of poor service to drive them away, and $5,000 in advertising to get them back again.” It’s a fact. I may be the Geezer with A Grudge, but I’m not the only person on the planet with a long memory or who would rather just move along than wrestle with convincing a company that I’d experienced poor service or had an unsatisfactory experience with their products.
A couple of days after our discussion, I remembered my last relationship with a luthier, back in the late 1970’s in Lincoln, Nebraska. For almost a decade, I’d fallen into the habit of buying guitars and, if I planned on keeping the instrument for any time, I hauled it to Lincoln and had my luthier setup the guitar at $150-250 per instrument. That seems like a lot for the time, but I was buying guitars idiotically cheaply from stoners and starving artists and had the margin to spare with most of my purchases.

Sometime in the early 80’s I brought in an old Gibson Explorer that clearly needed fretwork and a trussrod adjustment. The luthier had a couple of new employees, but I assumed that since I was an old customer my instrument would be serviced by the owner. I was wrong and the setup was awful. I lived about 75 miles from Lincoln and, while my studio was in Lincoln and I was in town for 2-3 days every weekend, I bought a book and made the corrections to the setup myself. Not only did I not complain to the store owner, I never brought in another instrument again and when my own customers asked where I’d have guitar work done I sent them to a shop in Omaha. I didn’t really know the shop in Omaha all that well, but I felt like I knew the Lincoln shop too well.

So, again my answer is “no.” I do not think the average customer, long-term or not, will bother to complain about lousy service. They’ll just move on unless you have set up some really clever system to almost require them to let you know how they felt about your product or service.

In my dotage, I’m taking a “guitar repair and construction” course at my local community college; mostly for access to the school’s incredible wood shop tools. After a couple of semesters, I began to wonder why none of the classes ended with the usual student course/instructor evaluations. Since the dropout rate in my class has been extraordinary, you’d think someone might care about student retention. After a little inquiry into the school’s policies I received the following response from administration, “According to policies set forth by both the State of Minnesota and MnSCU the tenured faculty are only required to assess their class once per year - and they can do so in whatever format they choose. Probationary instructors need to assess much more frequently. I should mention that we are in full compliance with the policies, so I'm not sure what you're looking to do with this.”

All I can say to that response is "Wow!" No wonder my experience with MNSCU's programs (from the UofM to Inver Hills to Southeast Tech) has been so marginal. It sounds like a system totally driven by teacher union contracts and management disregard with no system for maintaining quality-of-program or delivery performance considerations. There is no such thing as a feedback-free system that provides any sort of quality control.

Now I really feel like I'm officially in the Midwest, the home of the most mediocre educational experiences I suffered in my 30+ years as a student. It does explain the proliferation of for-profit schools here, though. Apparently, the solution is for the student senate to recommend RateMyProfessors.com and give up on the school administration doing any sort of job.

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.
