Its definitely available for bass, Washburn makes some of their basses with it pre-installed. As for tuning i agree having good technique and ear is very important, more so than good gear. If i have the option of building a bass that will be in tune perfectly ill go for it however. Having a fancy exotic bass is nice but if its not in tune, or if its difficult to play then its not going to sound good. This bass is going to be all about stability and playability. I have a good preamp, pickups and technique so i think the tone will be good no matter what wood it is. A friend of mine has a warwick with an all wenge neck (fretted) and he has played overseas in places like Dubai and tropical climates and such. He hasn't had a problem with the neck wood shifting and messing up intonation. Good tone on that bass too. I'm pretty sure about wenge for the neck now, i have a stingray and its neck is maple. Since wenge is quite different than maple ill end up with more bass tones to use.
I guess I'm kind of continuing my other post in another post.
Wow! Really? That's a really cool idea, but i have never seen any mention of it on Talkbass, so i wonder how big it sells.
If you like the Buzz Feiten system, and you can get it on your bass, i would say go for it.
It is sort of like a Earvana set up, but you have to slightly alter the tunings as well. It requires a good tuner, or at least they say it does. Never heard one personally, but they have been around for a while so it must do something.
