Abstract
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.
