I replaced my humbucker bridge pickup with a different one (humbucker as well) and now I have this buzzing when I'm not touching any metal part on my guitar (string or pots). I wired the pup exactly as the previous one was and did not touch anything else.
I checked with a multimeter and all seems to be grounded well (including the bridge ground cable) and nothing seems to be shorted. Once I touch a metal part the buzz stops completely.
Any suggestions? This is very frustrating!
