I currently own a pretty crappy Ibanez Soundgear, and it happens to be one of the extra-cheap models that only has the two middle pickups (p-bass pickups). I've done a lot of custom work to it however, including changing the bridge and nut, changing the tuners, modifying the paint job, and covering it in decently sentimental stickers. That being said, my goal is not to just buy a new, better bass, my goal is to improve on this one as much as possible. I've looked around for a while and can't find any answers to this question: Can I rout a new hole near the bridge to add a bridge pickup, and if so how would I install the wiring and create a hole to attach the wiring to the knobs? Would I have to switch to active pickups or could they stay passive? Would it maybe help if the new pickup I'm adding was active so it could be switched on or off, while the other pick ups are just constantly doing their thing, or would that create a short circuit in the signal on the way to the amp? I don't really know much about how the electricity actually TRAVELS from the PICK UPS to the AMP, so maybe what I'm asking is not possible. Basically, I don't want to drill/route an entire hole in my instrument where there didn't use to be one just to find out that there is no way to actually connect the new pickup to the previously existing wiring, because my bass was only built with two center pickups and I wish to add a third bridge pickup, possibly even a neck pick up at some point.
