Abstract: A magnetic pickup assembly is mounted from a support member bridging across the drum housing. The support member preferably extends diametrically across the drum housing and has slot means or the like permitting the mounting of the pickup assembly at different positions along a radial locus of the drum housing. In a preferred version the support member is of laminated construction to reduce vibration. The pickup assembly, in addition to comprising a pickup coil also comprises a series of ferromagnetic members secured to the drum diaphragm and also disposed spacedly along the radial locus of the housing; the arrangement wherein the pickup coil is adjustable to one of a number of different positions for obtaining different tonal outputs from the instrument.

Abstract: An array of magnetic pickup coils are mounted by a support assembly secured to the bridge of a stringed musical instrument. The assembly is preferably for use with a base violin or cello and is easily adjustable relative to the strings. The support assembly for the coils permits adjustment of the coils along each string, adjustment between each coil and its associated string, adjustment of the coil so as to center on the string and proper planar orientation between coil and string.
