If you need to shield your pickups, make sure you use extreme care. The best way to shield a humbucker is to put a nickel silver cover on it as it was designed. Using foils don’t do a whole lot as the electrical interference can go right through the top of the plastic bobbin. The same happens with single coil pickups when the shielding tape is put around the coil. The electrical interference can go through the top of the vulcanized fibre bobbin and you still have interference. Leo Fender used the metal pickup cover on the Telecaster rhythm pickup and put a bridge cover over the Telecaster lead pickup mounting plate. Many players have removed the bridge plate cover commonly called “The Ashtray” and one player that used it all the time was the late Albert Collins.
