ABSTRACT:
An electromagnetic pickup for stringed musical instruments has a primary bobbin having an elongated body with holes for receiving at least one pole piece or magnet and a coil of wire wrapped around the elongated body. At least one magnet is positioned in close proximity to the primary bobbin to create a magnetic field around the primary bobbin. In addition, the pickup includes a secondary bobbin having a body significantly smaller than that of the primary bobbin; a coil of wire is wrapped around the smaller body. The secondary, or hum-cancelling, bobbin is positioned in close proximity to the primary bobbin solely to cancel an audible hum caused by a power supply used in the amplification equipment and/or other environmental sources.
