Holy resurrection, Batman, but check this out.
This just came in, and evidently the previous owner never used the FX loop so he “fixed” the jack by doing this. I mean, it works ¯\_(ツ)_/¯
have you checked for any shorts at your footswitch? Make sure there’s no stray wires touching or too much solder underneath that could be causing an issue.
They’ll fit, I never have anyone ask for them as they don’t use batteries at all in their boards.
The switched power jacks are right at 13mm or 1/2”, so add a bit more for play and powder coating.
