I just installed a set of noiseless p'ups in my Jazz, and I'm getting a buzz that goes away as soon as I touch the control plate. The bass is star grounded, and just for giggles, I tried running a ground from the control plate to my star ground ring terminal--it didn't help. Anyone have any ideas? I thought about using fiber washers to isolate the pots and jack from the control plate, but I'm shooting in the dark. FWIW, these are 250k pots from the Stew-Mac J Bass wiring kit. Should I be using 1 meg ohm pots w/ my Noiseless p'ups? Thanks!
