i have a profile p-bass copy with a ground problem. I need help! I have a wiring diagram for my bass and everything looks ok, except that the last owner ran all the ground wires to the body of the pots instead of to the actual ground terminal, and one of the pots is a 250k and the other is a 500k, and the ground wire doesn't actually attach to the back of the bridge, but then it doesn't look like it ever did, it just kinda sits there and you bolt the bridge back on over it. does any of this sound like a problem? I know electronics and wiring but not where it applies to a bass. where would i start to look to trace down a ground problem? there is only one shop in town that does repairs and he's an a$$. i dont like him and he does everything half a$$ed. please, please help?
