ABSTRACT:
An electromagnetic pickup for a musical instrument (e.g. a guitar) having a plurality of ferromagnetic strings coplanar and parallel with each other, the pickup being adapted to be mounted adjacent to but spaced from the strings includes an elongated electrical pickup coil having a longitudinal central opening, the opening having a length at least as great as the span S of the strings. The pickup also includes an elongated main permanent magnet having a length L such that L>S and an elongated ferromagnetic shell having a length at least as great as S. The main permanent magnet, the pickup coil, and the shell are assembled together in an electromagnetic pickup assembly in which at least one side of the pickup coil is enclosed by the shell, and the main permanent magnet is parallel to the central opening of the coil; the assembly generates a magnetic field which encompasses at least one portion of the pickup coil. A housing mounts the pickup assembly on the musical instrument with the top of the coil facing the instrument strings, which intercept a portion of the magnetic field.
