Butterflied original fender J bass pickups with seymore Duncan's quarter pounders, put a six point switch to play with in-phase/outofphase, parallel/series, and isolate each pickup. Currently adding a piezoelectric bone bridge pickup to put some active power on the harmonics.
This thing doesn't sound like your usual bass.
If you like it I can customize yours.
Location flexible, I'll drive it to your gig or house.
