My bass has a dimarzio will power p pup wired to a volume knob, to a redeemer circuit active buffer. Whether Im using a cable or my digital wireless I get alot of buzz and a snap when I touch the metal parts of the bass. Everyting is grounded to the output jack and I've tried everything I can to get rid of the buzz and snap. If I wired a small cap from the pickups hot to ground, to low pass at 10khz, would this fix the problem? I've resorted to using a noise gate live because lighting makes my bass so noisy.
