Hi all, I've been around the block a few times, I know my way around tube amp repair. I'm embarrassed to say that this simple wiring job is driving me bananas. A few months ago I decided to re-build my p-bass electronics - new pots, capacitor and output jack. The problem is that I can't seem to get the tone knob working properly - that is, the tone is always rolled off. I've re-done this wiring twice already with no luck. Tonight I came close - getting the tone knob to behave properly before being attached to the pick guard. The wiring is standard - http://cdn.seymourduncan.com/images/support/schematics/std_pbass.jpg However, at first, with the tone capacitor grounded to the tone pot chassis, the pot didn't work. I saw a picture on the mojotone website with the cap grounded to the volume pot, at last - the tone pot works, however, the bass played a very reduced volume (poor ground). When the pots are grounded together I get full volume again, and the tone pot ceases to work. I'm using a foil-lined pick guard. Any help is appreciated!!
