Solid brass plate with black foam rubber pickup riser and cloth covered ground wire. Fits into the cavity on the body under the pickup to provide shielding from buzz, hum and electrical noise. Measures 3.510" long, .761" deep.Exactly the same part used on USA Vintage Series Jazz Basses. Comes from the Fender factory with a black cloth covered wire soldered on; the other end of this wire is simply soldered to the back of the first volume pot where the other black wires meet in a 'star grounding' arrangement. There's a piece of black foam rubber stuck onto the top of the plate; this serves as the pickup 'riser' when you loosen the four screws on top of the pickup. Brand New. Genuine Fender 0019662000.
