Kitchen aluminum foil as cavity shielding ?

    I ordered parts for my project/experiment guitar-bass project. But, I forgot to order copper tape. I also thought that its just an experiment guitar for now and didn't want to spend more. I was thinking of gluing kitchen aluminum foil to the cavity sides and pickguard. Would that work?

    Thanks!

    Yup. I usually use it with layers of copper for heavy shielding.

    Aluminum foil works, but get a roll of copper snail and slug tape at your local hardware store. it's got adhesive on one side, so there's no glue to mess with. It's only about 1.5" wide, but you can just slightly overlap it. You can solder to it, unlike aluminum. And if you mess up, it's easy to pull and start over, but once it's in there it stays put nicely. Works great!

    Aluminum foil works for the back of a pickguard but it is a bit annoying to work with for the cavities, because it is hard if not impossible to solder to.

    Yup, it will work but It will be more finicky to work with.

    I use aluminum tape used in HVAC applications. Get a large roll at the hardware store for less than 3 dollars.

    They don't sell slug tape around here. :(

    I'm very glad I looked at this post. I had no idea that the copper tape was used for slugs. It's on Amazon if you can't get it locally and it's cheaper than Stew Mac.

    I read somewhere that the only issue is that the adhesive is not conductive.

    That's the first time I've heard of slug tape. A quick search shows I can get it locally, 100 mm wide, apparently.

    +1 on this... I use the heavy duty aluminum foil on the back of the pickguard, but go to the local stained glass store & pick up a 1ft sq sheet of copper foil -- that way you can cut to fit the cavity bottom and sides and avoid overlaps. It may take a little longer to measure and cut-fit, but IMHO you end up with a better result. Also, while the adhesive on the copper tape and foil is supposedly conductive I still spot-solder any overlap just in case...

    Yep this tends to be a bit thicker than kitchen foil and easier to work with therefore.

    Make sure that you use the non-stick kind. That way the bad notes will "slide off" the foil and never actually get to your amp. You'll sound 100 percent better.

    What does that mean? I'm not getting a clear mental image, can you please clarify, thanks.

    I think he means fold a corner over, so the bare side provides continuity.

    Yup, this. You can't solder aluminum, and the duct tape won't have a conductive backing, but it isn't hard to get good conductivity across all of it by simply folding a small corner over each when applying it so that you have metal-metal contact across the whole shield.

    I get it now, just where it overlaps (duh)
