I'm getting some buzz from my Peavey Falcon with a set of Bill Lawrence 280's and a 290 noiseless pickups. Buzz goes away when I touch any metal on the guitar. I've had the multimeter out, continuity seems to check out. I did modify one thing recently. I resoldered the six ground wires to the back of the volume pot. I also put aluminum foil tape under the pick guard (it had none and also has no shielding in the cavities). The original wiring had jumpers between the switch and pots for the ground connections which are still in place. I have since then read on the Fralin website that this can be bad for noise. Any truth to that? Any other ideas on what I can do other than shielding the cavities with copper foil?
