I've got a Jazz Bass American Deluxe V, and I've been considering putting a musicman pickup right between the two pickups already there. I've seen some posts on here about it, and seen some videos and was quite pleased with the results. I want to have the widest variety of sounds in my bass possible, being that I do shows locally, and am going to school for music. Do you folks have any advise on wiring, etc.? The bass already has a preamp in it, but I can switch it out if needed. Edit: I should also point out that the pickups can switch between active and passive, so how would I go about picking out a pickup?
