I do not recommend the shielding paint and here's why: a test was performed on a painted cavity and showed very high resistance (3.41k ohms) resulting in a low shielding effect. When upgraded with foil shielding, the results proved very low surface resistance (.07k ohms) - Low resistance = High shielding effect. Grounding cavities and your bridge are your first line of defense.
Copper tapes and foils provide an easy-to-apply, time saving, cost effective way to shield against EMI/RFI radiation. The tape and sheets are conductive throughout, including the adhesive, and offers mechanical, electrical, and thermal values to meet shielding requirements. |

Copper Foil Shielding Sheets
Thickness of Foil: .003" = 3 thousandths of an inch
Conductive adhesive-backed copper foil sheet(s) for the reduction of EFI and RFI static. Use it to line your control cavities, pickup cavities, and the back of your pickguard. |
| If you're only doing the cavities of a typical Jazz bass, for example, you can do it with one sheet (7" x 12" to be exact). When shielding pickguards, the foil only needs to be applied in the area of the control cavity. If you've never shielded cavities before, grab two to cover for errors.
Rolls of Copper Foil: I can get these in rolls but it's usually a special request for anything over 10 feet. If you need an uncreased roll of copper foil the minimum length is 5 feet and anything over 10 feet please contact me first so I can request it from my supplier.
Allparts offers 12 inch wide x 10 foot rolls of copper foil:

Copper Foil Half Sheets - .003" thick
Perhaps you only need a half sheet for a portion of a pickguard, or whatever. But this is mainly being offered for the bottom of the cavities. This part of the shielding job can be difficult for |
| some. If you haven't done this before it can be a daunting task, but I'll try explain it and show photos (soon) so you'll be able to do this yourself with relative ease. Basically I'd like to able to provide precut cavity bottoms but the shapes (plan view - top-down view) of cavities vary even within same model basses, enough so that I can only offer half sheets here for the time being.

Precut Copper Foil Cavity Wall Strips - .003" thick
The side walls of the cavities of a typical bass are 1-1/4" wide in the control cavity and 3/4" wide in the pickup cavities. The following copper foil strips are cut to 1-3/8" each and 7/8" each, with more than enough length so you can line the walls of at least one bass, or have enough just in case you mess up one of the strips during installation. The added width of the strips is to overlap onto the foil that's attached to the bottom of each cavity. Basically the equivalent of almost a full 8x12 sheet. You can buy one sheet yourself, cut it yourself, and save 2 bucks, or buy this and it will arrive ready to install.
