Fender and Gibson pretty much set the mold for guitar shapes since the mid 20th century, and they've been the standard for the most part. Whenever someone comes out with some funky body shape or design, Guitar players run away like a child being threatened by cooties.
Bassists however seem to say "ok" whenever some company does a new ergonomic idea. Perhaps its because early basses, like the Precision are iconic, but it does have it's issues; it can be heavy and a bit ungainly. So bassists look at form and function a bit more than tradition.
Now yes, there is an extreme to that, in a certain sense, but even since I started playing guitar, I would see some cool bass guitar, and say "how come they don't do that kind of design for an electric 6 string"? Yes, I have covered this before with the blog post covering the Rickenbacker 480. But I still ask why. Here are a few shapes I would have loved to see incorporated as a regular 6 string guitar:
Kubicki EX Factor.
These basses play really well, and the neck is composed of 1/16" laminates, making it super stable! The cutaway area, if you can call it that, is pretty much non existent, giving super access to the upper frets. Phil Kubicki worked for Fender in the late 60's, and did George Harrison's Rosewood Tele. Considering he had a background in guitars, I'm really surprised he never did an electric like the EX Factor.
Ibanez Ergodyne
I have to say this was really adventurous, even for bass players, with the super curvey shape I'm surprised I didn't see these more back in the day, considering that Ibanez had the lock on quality mid priced ($600-$900) basses, especially in the hard rock and metal genres.
Mark Sandman Premier Bass
Mark Sandman of Morphine did his own thing; 2 string bass that got a lot of use like a slide guitar. It was pretty much a pawnshop prize. When players were going to hyper expensive 5 strings he went his own way. Waterstone Guitars did a re-issue of his bass (as a 4 string) and decided to do a matching guitar as well.
I'll admit this is where translating a bass guitar shape to electric 6 string didn't work out. More than likely the designers just re-configured the bass guitar body shape to work with regular guitar parts. Scale is a factor, The body should have been dropped down a bit in size to make it more proportional. The pickguard is also a miss in my book.
So while there's misses, here's one that nailed it
Spector
It's so hard to believe that Ned Steinberger, of the headless Steinberger guitar company fame, designed this in the 1970's! It probably set the standard for the ergonomic bass designs that came later in the 1980's. Kramer later took some interest in Spector, and actually did make these basses in the 80's & 90's. They also did some guitars for the guys in Skid Row, as well As Joe Perry. Those were more along the lines of Classic Double cutaway designs like Les Paul Jr's. But many years later:
With all sorts of wild guitar companies (strandberg, for example) doing designs that they say are following ergonomics, I'm still always perplexed why things haven't really progressed. I guess bass players are more forward thinking..
