Very cool!
You know you have to buy this bass now, right?
I'm curious about the wiring too. I mean really, aside from rock'n'roll excess, why four pickups? Maybe they're RW/RP or something - to act as a pair of humbuckers in certain varitone settings?
If he's close by, and you go over to audtion it - bring a screwdriver, compass, and a camera!
Curious minds want to know...
