I have a beautiful Paul's Guitar that is very noisy. The hum goes away if I touch any metal on the guitar, including the strings. I'm wondering if there is no grounding at all on this guitar. The wiring diagram for the Paul's Guitar says "solder pickup harness shielding to tone pot casing" but I see nothing attached to the tone pot casing. I also know that typically a ground wire is run from the volume pot to the bridge, but with the Paul's Guitar there is no conduit in the wood to even get to the bridge.
Any advice re what I can do to fix?
