My beloved Squier Tele with DiMarzio Virtual T pickups seem to have developed a grounding problem. It hums like crazy now if I don't put my hands on the strings or on the control plate.
I took a look at the soldering, and it looks fine.
I have had some problems with my 3-way switch, and I think I'll replace it and see if this solves the problem.
Anything else I should check?
