wondering if it's possible to cover up the body cavities, the one where all the parts go (i.e wires, pickups). not COVER cover, but like a new surface. just line it up with foil or something. anyone know if that's a bad idea? or if it could affect something like tone or anything else? i wanna cover it up, it might look a bit neater inside. better than now, it looks all bubbly.

Sure, that will work, just make sure not to short out connections if you use something conductive.

are you talking about shielding your control cavity? you'll want to do that with copper tape

check out www.guitarelectronics.com , theyve got pretty good prices on shielding tape
