Abstract
A piezoelectric crystal transducer defines a unitary part of a low profile saddle member adapted for interchangeable mounting in the bridge portion of a stringed musical instrument while obviating external modification of the instrument itself. In a preferred embodiment of the present invention, the body of the saddle is molded or potted around elongated piezoelectric crystalline bar segments to form a unitary saddle in which the bar segments traverse the substantial length of the saddle in a direction transversely of the extension of the strings over the saddle with hook-up leads or wires extending from one end of the bar for connection to a suitable cable leading to a conventional amplifier or loudspeaker system. The transducer is constructed to respond to stresses produced by string vibrations in one or more dimensions yet is completely shielded from external electrical fields and minimizes interference with the acoustical circuit of the instrument.
