Hey, I'm shielding my S470 cavity's at the moment, I'm using sticky back aluminium tape, any tips to give me? I know about grounding the shielding to the back of the volume pot. I've just done the back control cavity, onto the pickup cavity tomorrow.
Sounds like you've got it pretty much covered. If the adhesive on the tape isn't conductive make sure each piece is connected electricaly, and the shielding for the cavity and the cover plate touch somewhere.
Either works, i've used aluminium foil and copper tape on guitars, both work well.
