I got one of those new snazzy Bongo basses and I was experimenting with the tonal variety the other day. I was able to dial in a pretty good Jazz Bass sound, but I think with a single-coil I could get a little closer. I thought about putting a coil tap switch on one or both pickups, but I haven't opened the bass up to see if this would be possible. Does anybody know how many leads the pickups have (2 or 4)? Are these wired in series or parallel from the factory? Any advise/cautions that I need to hear before I even consider this? Danksalot!
