    Dear all, i used to use Copper foil for the shielding in my project, but after seeing the clean and neat result of Mr. Nino's work, i ordered my first Shielding paint from Stewmac, a little question, when i use cop foil in the old day, i need to ground it and usually i will have a wire either branched off from the grounding wire underneath the bridge or just a seperate wire soldered to on the copper foil. but do i need to do the similar thing when i use paint?
    or just lead all the g wire from the pot and the bridge to the jet and leaving the painted control cavity not connecting anything be Ok?
    urgent
    please help :help:

    Should be fine without grounding the actual paint.

    No, the paint must be grounded to have any effect. When using paint, either screw a ground lug though the paint into the wood or, if in a bass with no pickguard, make sure the pots contact the paint where they pass through the top wood.

    Well I was going to argue that I've shielded basses without having to do that, but then I remembered that the shielding I've done always touches the pots at some point, so I guess I can't. OK, I stand corrected.

    Thanks for the input, i hope the paint can do a better job than the foil, at least its dark flat finish is cool looking..haha :bassist:

    Copper actually does a better job, if the install is correct. But paint works well, too.
     
  7. another good suggestion...I think...

    apply a small patch (size of a US nickel...or an aussie 10cent piece) of the copper tape first...solder an earth wire to it...and then paint the copper as well as the cavity...this will give you a really good contact between the paint and earth (ground)
