ok so i have a U.S. fender p bass with the p and j pickups, and i can't seem to figure out what the problem is and why i get a slight pop when i touch the strings, bridge, volume or tone knobs, screw on the pickups, or the poll pieces. i even taped over the poles with electrical tape. so thats not the prob. I took of the pickguard and it looks very similar to the other post about the static squier, heavy shielding on the pickguard, and also a non-conductive spray on the inside of the knob cavity.every wire looks good, and fuctions perfectly. Do i just have noisy pickups since they are single coil? i don't have any lights or electronics that are creating the hum nearby either. help is much appreciated!
