Abstract
A pickup system for an electrical musical instrument having strings includes two pickup windings to respond to playing of the strings. A third winding is included. A switch connects any of the three windings in electrical series with either of the remaining two windings so that any of three respective pairs of connected windings can be selected. The windings of each of the respective pairs are connected such that interference such as 60-hertz hum is canceled.
