I just started this summer project with my Epiphone Les Paul Special II, making some kind of overhaul by changing the nut, the bridge, and the electronics.
I took my guitar completely apart and now I am plagued by questions. I see that there are some areas that are not completely leveled or smooth in the place where the neck meets the body (it's a bolt-on). Should I sand this so that it's leveled and smooth? Could the guitar lose the capability of being in tune and have good intonation if I sand this?
I got another surprise too, there's this cable that comes from inside the body and it's labeled bridge ground. Isn't that dangerous? I mean, have I been at risk by playing this guitar while having it grounded to the BRIDGE? What's this cable doing there and what should I do with it if I'm planning to change the bridge and the electronics?
