Hi, so recently I put some p bass pups on my jazz in replacement for the neck pickup, I have have kept the jazz bridge pickup as love how punchy it sounds. The reason I have done this is because I love the tone of pj bass, but prefer the playability of a jazz. So basically my question is. When I have the bridge pickup volume completely off the neck pickups work fine, but as soon as I turn the volume up on the bridge pickup the neck pickup sounds like the volume reduces by around 3/4, but only on the E and A string. Is the wiring different on jazz than a pj bass? Any help would be much appreciated.
