I spent a bit of time with a bass player who played a Variax bass, I have to admit that as much as I wasn't too attracted to the design of the bass and the neck, the tones were very very sweet and it performed flawlessly. One of the nifty tricks he showed me was a program he integrated into the software that allows him to asign individual pickup assignemnts to the strings he plays (including effects) with no discernable latency ... My jaw dropped ... E string pure Pbass thump, D and G is that Spector sound with big clarity and the G string pops like a Musicman with a flanger sound mixed in or goes in oblivion through a Kaos padd sim. The last time I saw this form of string assignment system was on one of the Gibson 'robot' guitars Brendan Small used on Metalocalypse. But it got me thinking, how many times I've recorded tracks doubling on a few basses for the engineer to partition the bass track in the mix because he liked one bass for certain portions and another for others. It got me thinking that as most of those times those parts were related to active and passive basses, are there any manufacturers out there who make a selectable active coil system? Let's say I want the first 2 pairs of coils on my JB bass passive and the bottom two active running through the Preamps EQ ?
