    Aluminum shielding

    I get a lot of electrical noise in my house, so I decided to shield my Warwick today. Took out the pickups and knobs, lined all with aluminum foil, and grounded each cavity. All the noise is 100% gone whether I'm touching the strings or not. This was the cheapest and easiest mod I've ever done, and yielded the most night & day results. Go figure.

    Heavy gauge aluminum foil is a go-to if you don't have access to copper foil.

      I used cheapo Reynolds wrap.

        Cool. Good info. And like you said, Reynolds Wrap is cheap.

          Yeah, definitely a perfect alternative to copper tape if you ground it reliably. What method did you ground it with?

            Warwicks have a pair of large springs under each pickup. I put the end of a ground wire underneath a spring in each pickup cavity, then soldered the other ends to the tone pot. For the control cavity, the pots are in direct contact with the foil.

              Does aluminum cause any bleed of higher frequencies due to Eddie currents? (I know it's probably much less of a problem with a bass than an electric guitar.)

                On my bass, it had little to no affect. I usually hear about any high end loss, but it may be affecting frequencies I’m not occupying.
