    Hi all!

    I just swapped my pickguard and thought it was gonna be a simple thing, but when I got everything put back together, I seem to have created a ground issue. I can barely hear a note, unless I touch a knob or the bridge.

    Please help. Thanks in advance!

    I had this same problem on a Glaub. There is a ground that should be there and on mine it was a piece of foil on the back of the pickguard. I bought a new one that didnt have it and i had the same issue.

    I did exactly the same thing when i got a PG for my DD from Jeannies.
    It took me a few mins to figure out it didnt have any foil on it.

    Well it was a few years ago and i was about to start a thread at the time so almost.

    It wasnt until i put the original PG back on and the hum went that made me look at both and then it was pretty simple to sort out.
    Until that point i thought i had broken a pot, so i almost got the award. Just glad no one ever found out about it :bag:

    This is why control plates and pickguards should never be used for a ground return. If one of the knobs or output jack loosens, you can get intermittent behavior.

    While you got the guts of that thing open, I would run ground wires to all common ground points: the foil will be the backup.

    I'll just do it now! Thanks, Matador!
     
  13. i was wondering, all parts are grounded (including the foil) to the pot and then to the ground on the jack?

    You may be able to see in the photo of my OP, but if I remember correctly, both leads from the pup go to the volume pot, then the ground goes from there to the jack. The bridge ground also runs to the output. That's what threw me off. The tone pot didn't seem to be grounded.
