I was thinking the tape will be visible since I'm not using a pickguard.
Copper tape works better than shielding paint in my experience. Make sure that you ground all cavities together with a spare wire. I'd paint it and then put the copper tape down though, then the pickup over the copper tape.
I used to be a shielding paint guy. The first guitar I shielded with the stuff is great and is still going strong now. However, after letting that same can of shielding paint sit for about 5 years I decided to use it anyway on another guitar. Needless to say, I do not know if the paint expires over time or what but it does not work so well in that guitar. It's grounded, all shielded cavities are connecting, etc. Should have gone with copper tape. I am now trying to locate some of this copper tape that has a conductive adhesive for my next guitar.
I bought a roll of it from China for about $25 shipped. It was enough to do about a dozen guitars.![]()
I have been looking on ebay trying to find some that have conductive adhesive. The English is a bit shaky on a lot of the posts and so I started reading feedback. I have not found a seller who advertised conductive adhesive or double sided conductive copper tape, etc that hasn't had negative feedback saying the adhesive wasn't conductive. Did you order yours from ebay?
They're a bit expensive for some stuff, but their stuff is usually pretty good.Awesome, I trust the StewMac.
