Okay, so the first bass build can be viewed here. This was more just trying to get an understanding of the fundamentals. Although, I did add some cool touches to it with the laser-etched top and the piezo bridge pickup Now, just to give you some background, I'm an industrial designer by trade. I've worked on designing all sorts of products ranging from faucets to sunglasses to headphones to furniture. My basic job function is to make stuff that fulfills a user's needs, looks cool, and is cost-effective to manufacture. This thread will outline the process of a prototype bass design that I intend to work on. Back in the 1950s, almost all of the decisions made around Fender's first bass guitar were centered around reducing cost. There is nothing wrong with this. There's no point in making something that is too expensive for anyone to afford. But it was done at the expense of user comfort. My goal is to improve ergonomics for the electric bass using improved body shapes and neck profiles. My target "customers" are serious bass players who practice a lot. Music students specifically. People who practice for 2-3+ hours per day. I'm not talking noodling, either. I mean disciplined practice with the express intent of improving on the instrument. These players need an instrument that does not lead to RSI (repetitive stress injury) so the thing just needs to fit like a glove. Another submarket that I intend to target is 45+-year-old players who have health issues and are struggling to play their current instrument...people with carpal tunnel, back problems, etc. etc. If they don't find an instrument that caters to their ergonomic needs, they face the possibility of never playing again. Please note, I don't think I'll actually mass produce or sell this product, but it's useful for me to have an idea of these parameters. They will greatly inform the design....otherwise the design decisions will be made too subjectively. I am fully aware that there are a few luthiers who have designed instruments in this particular segment. But I still hope to bring my own perspective to the table. Even if it's a mild improvement, I'll be happy. So to start, let's analyze the problems. I know this stuff is probably really obvious to you more experienced luthiers, but it's important for me to lay out the problems so that my decisions for building are well-informed. 1. left and right hand bending=carpal tunnel. One problem is that basses need to sit at a 45 degree angle relative to the floor in order to make sure that both wrists are in a neutral position. If they sit parallel to the floor, you get some very awkward bending due to strap height. Even still, some body shapes and neck profiles are not very easy to work with ergonomically. 2. Poor posture in general. This is largely due to bass players having to look at the fret board while playing. When you have poor posture, the muscles in your neck and your shoulder cramp up. That tightness eventually makes its way down to your wrists, which leads to issues with playing the instrument. 3. Here's an example of "proper" technique. But even still, notice how out of the way this guy has to go to get his bass in a good position. His legs are splayed out, one leg is much higher than the other, and there's no way for him to see what he's playing in this position: Now that I've outlined the problem, I'll start to post some preliminary solutions. I'd love your feedback and input on this.
