Wiring error... buzzing that won't go away unless I touch the volume or tone knob.

I have a newish guitar that has had the stock pickups swapped with duncans... never noticed this until I plugged into an amp without a noisegate.


I'm guessing maybe a ground thing between the 2 pots and jack? Unfortunately everything visually looks fine.

No . . . that means that the ground between pots and jack is good. I'd check the bridge ground. I don't mean bridge pickup. I mean the bridge itself.
See what happens when you touch the strings or bridge. Does the noise go away?

No change when touching the strings or any part of the bridge (floyd)... block, claw, anything.

I've felt up everything on the guitar now, I noticed it also goes away if I touch the jack plate or set screws for either pickup but nothing else.

There should be a ground wire from the claw to the pots, then the pots to the jack. If all of those are there, there should be no buzz. Unless the internal bare of the pickups somehow came loose?

Doublecheck to see if the bare is matched up with the green as well. I've seen some guitars where someone changed the pickups and just snipped the bare wire at the sleeve, running just the green to ground alone.

There's your problem. The bridge, and thus, the strings, aren't grounded. Like DrNewcenstein said, you need a ground wire from the claw to ground. Somewhere.

Thanks everyone... the bridge did have a ground wire going out to a screw/lug terminal going in the body that was joined to a few other black/ground looking wires so I assumed it was grounded. Did a continuity check with a meter and no ground so ran a new one. Guitar has mini-pots so I'm guessing they did that to save space and make things tidy but overlooked one major step. Doh.
