Congratulations on joining the "Fix it if you can" club.
Maintenance or repairs on the wiring of hollow-bodied guitars is even more fun, especially spending ages with a bent piece of wire trying to hook the loose one to solder it back in place (then comes the fishing game to thread the tone control, or whatever, back through the f-hole and get the end of it sticking out of the body so you can fit it back where it belongs).
I think I may have just convinced myself that any future guitar purchases will be Strats; once over the initial fear of tackling the unknown, they're really easy to repair or upgrade.
I wish this forum had a "block user" feature. Possibly I'm not the only one......
