Hi
I have some problems with my PJ bass wiring. When you fully close the potention meters, a loud buzz occurs. When you slowly open the potetion meters, the buzz dissapears and you can just play the bass. I think I did something wrong with the grounding but I don't know what. The pickups are seymour duncan quarterpounder P pickup and a seymour duncan hot Jazz pickup.
I included the schematic that I used. ( I made it myself )
