I am totally ripping my hair out on this one. Now usually I am pretty good at wiring up guitars, but this one's outsmarted me.
I picked up a project semi hollow body guitar and finished it up a couple days ago.
Strung it up and I am getting tons of noise & hum. It quiets down when I touch any of the metal parts, so I was believing it's a ground issue.
All my grounds are joining at a single point, and I have continuity between all parts (both humbucker pickups, the single volume pot, the single tone pot, the bridge, the switch and the jack.)
I pulled it all back out and re-checked all my wiring and solder points, and everything is as it should be.
So I came to the conclusion it must be a shielding issue, since it's in a semi-hollow, there's no shielding paint/tape. So I ordered a good length of shielded wire (the single conductor style with the metal braided sleeve like used in a lot of vintage guitars) and completely rewired the entire guitar with it (including removing the original pickup leads and replacing them with the shielded wire.)
The noise is still there! These are new Bournes 500K pots (though I also tried some known good used Gibson 500K pots to eliminate them as the culprit) and a Switchcraft 3-way toggle and Switchcraft jack. The capacitor is a Vitamin Q 0.22 cap. I have tried a different output jack, but I not a different switch (I don't have any other switches, but have tested the continuity of the switch and it shows good.) I have tried removing the tone pot completely from the circuit as well. I don't know what else it could be. Anyone got any ideas? What am I missing?
