ABSTRACT:
The preferred embodiment relates to a musician operated electric guitar having a plurality of metal strings and at least two pickups for transforming mechanical vibrations of the metal strings into electrical signals proportional to such mechanical vibrations, where the electrical signals from the at least two pickups are added together into a single guitar output circuit. The preferred embodiment is an apparatus for facilitating the electrically quiet, one touch electrical switching in and out of the guitar output circuit selected combinations of the at least two pickups electrically switched in and electrically switched out of the guitar output circuit, comprising (1) a plurality of discrete switches; (2) an encoding means interconnected to each of the discrete switches for sensing which of the plurality of switches has been depressed and creating a plurality of distinct control signals, one distinct control signal for each discrete switch depressed; and, (3) a plurality of automatic switch means, each automatic switch means being interconnected to the encoding means and interconnected between one of the at least two pickups and the guitar output circuit for switching its pickup into and out of the guitar output circuit responsive to at least one of the distinct control signals received from the encoding means. The depression of each of the discrete switches thus causes a single combination of the at least two electrical signal sources electrically switched in and electrically switched out of the guitar output circuit to become so switched in and out.
