This humbucking pickup is suitable for use in most Epiphone/USA Les Paul, SG, ES style guitars or similar guitars for both the neck and bridge positions. It is made of genuine Wilkinson parts and has 50mm/52mm pole spacing for the neck and bridge, with wax potting. The Alnico V magnets produce a classic vintage tone with incredible focus and dynamics. The pickup has a magnet made of Alnico V and a D.C. Resistance of 7.6K for the neck and 14.1K for the bridge. It also has four conductor wires, with the black wire serving as ground, the yellow wire as hot, and the red and white wires for coil splitting. The package includes 2 pickup pieces, although our screws may not fit your guitar, so please use your own if possible.
