Many styles of electric guitars require P-90 pickups in the neck and bridge positions that are wax potted. Some common guitar models that use these pickups include the SG, Les Paul, Ernie Ball Axis series, Epiphone Casino, and Fender Tele. The M series of Genuine Wilkinson parts is manufactured in China and distributed by Musiclily. This particular pickup is known for delivering the iconic power and sound associated with its style. The magnet used is Alnico 5, and the D.C. resistance for the neck is 8.1K (± 0.5K) and for the bridge is 9.8K (± 0.5K). The hot wire is the white one, and on the back of the pickup, there are markings indicating N for neck and B for bridge. The package includes 2 pieces of pickups. Please note that our screws may not fit your needs, so please use your own if possible.
