I recently fitted an EMG BQC system in my Warwick Corvette. Already had 2 x EMG J pups. I also fitted a new output jack at the same time. Wired it all up and there was audible buzzing/distorting when operating at any volume, more when boosted. Not dire, but EMG systems are supposed to be dead quiet!
What am I supposed to do with the bridge ground? I read that you should disconnect it from the output jack, but when I did that, I got immense
Now, the electronics cavity is shielded in copper foil, the bridge ground is soldered on top. Should I desolder it?
My adjustable spanner is too big to properly firmly tighten the output jack. Not sure if that could be attributing to the issue? What kind of spanner fits anyway?
I've contacted Rick at EMG and he suggested a few things, one being I need to make sure none of the circuit boards are touching the copper foil and to wrap the battery in electrical tape. Well, the circuit boards looked ok (it's a plastic housing anyway right?) and did as instructed with the tape, but it had no effect.
I'd really like to solve this issue myself but am out of ideas
My guitarist is busting my balls to get this sorted as it's interrupting our recording process, any advice greatly appreciated!
