HELP! I need somebody to help me out with a proper wiring diagram for a Fender P/J Bass. I've installed and replaced many pickups over the years but this one's giving me a major headache. After the 4th time rewiring this Bass and closely following the wiring; the neck pickup goes up to approximately 9 but when turned all the way up (10), it cancels out everything else; the times before that it would just hum and buzz like crazy every time I touched either one of the volume knobs. (grounding issue for sure). If it matters, I'm using a Custom shops 60's Jazz pup for the bridge and a Custom shop 63 P pup in the neck position. Thanks.
