So I recently put together a Tele partscaster and everything is great except a weird ground issue I cannot figure out. Essentially, the guitar is dead quiet UNTIL you start playing, then, especially if you hit something like an open note or chord and let it ring, you will hear very prominent EMI buzz. If you touch something like the volume pot or the metal of the output jack it will go away, and it is reduced by having more of your fingers on the strings, but I don't understand how it goes away completely if you take your hands off and don't pick a string. It is as effective as a noise gate.
This is a typical 2 single coil pickup Tele with a metal control plate, one volume, one tone and 4 way switch (has an added position for series mode). I shielded all the cavities because I have a lot of EMI to deal with that can be especially aggravating with single coils. I've confirmed that all metal components, ground solder points and the shielding have continuity with the sleeve connection of the output jack, and measure a slight resistance between 0.1-0.4. If I measure from the neck pickups metal cover I get a wildly diverging resistance but I assume that's because of the finish on the metal.
I'm stumped!
