Looked through some threads here and couldn't find an answer to my inquiry. I have this FSR P Bass special in seafoam green that I love (in appearance). However, I don't like active pickups so I decided to wire it up passive. I have this vintage PAF Dimarzio Precision pickup that I wanted to use so I wired it with a Fender Jazz Bridge pickup in a passive p/j configuration. Did this by using 2 of the 4 leads on the dimarzio (red - hot, green - ground, black and white taped together and not hooked up). I wanted individual tone controls for each pickup so I wired it up with a master volume, tone for each pup, and a 3 way switch instead of a blend. Solo, each sounds great. I accommodated for the volume difference using higher pickup height on the jazz pickup. Together, they have a tremendous volume drop and a tone that sounds similar to a wah pedal completed activated. Almost, 80s synth-ish. Not what I'm looking for. Haha. Anyone have any ideas outside of different pickups? Maybe a wiring change, etc. Thanks!
The pickups are out of phase. Just switch the wires on one of the pickups and that should fix your problem.
Better yet, purchase a humbucking J pickup from DiMarzio. The Area 51 pickups are very vintage-y. The J model growls. The Ultra-Jazz is more "modern" in tone, and you won't have to raise it up. This will keep everything in phase and keep the bass as quiet as possible.
The Dimarzio Ultra Jazz pickups are real nice. I'm selling my set only because I'm using the Delano pickups with the Music Man size pole pieces for a Godzilla like punch.
But just don't cut the blue wire......errrr... the red wire......yeah.....the blue wire. Bad bomb defusing joke, sorry.
Blue wire? Whew! That means my Rickenbacker HB-1 was simply wound with a different wire and magnet orientation, and it wasn't a bomb (not to be confused with being the bomb), after all!!!
Yes and no. If the poles pieces are grounded properly, then no. If there is a hum when you touch the poles on one pickup, then that pickup is the one to swap. The problem you are having is a common one, and it is caused by having the pickups out of phase. The tone gets thin because the pickups are canceling each other's signals out.
I have SD SPB-1 P and STK-2 Jazz pickups on my P/J. It was weak sounding then I read to swap the ground and signal wire from the J pickup to it's pot. Now works very nicely.
