I switched out the stock pickups in my Squier Affinity P-Bass about a year ago for Seymour-Duncan Quarter Pounds. I love my tone, but the pickups are so hot that the noise drives me insane when I stop playing. (I do know it's a grounding issue; putting my fingers on the bridge, strings, or knobs stops the noise.) So today I decided I would research shielding. I decided to go with copper tape from Stewmac rather than the paint, but a question I couldn't find the answer to on Talkbass was how much copper tape I should buy to shield my (1) cavities, (2) pickup covers, and (3) bridge area. Any suggestions? Would one roll of 3/4in x 180in do the trick? Thanks in advance! And if anyone has some advice it'd be greatly appreciated seeing as this is my first shielding job. EDIT: To be clear, my P-Bass only gets too loud when I roll up my tone knob. That's not unexpected but I read a lot of posts where people say a passive bass should have little to no buzz. I believe mine has a little that just intensifies with the extreme treble boost from the tone knob.
