ABSTRACT:
An electronic amplifying apparatus intended for electric music instruments (primarily guitar), with switchable circuitry offering an improved, specialized circuit for the enhancement of solo playing in addition to customary simple amplification. In the lead (or solo) mode of operation, the circuit will synthesize particular sustain and distortion characteristics and add them to the tone of the instrument (guitar, electric piano, microphone, etc.) to produce a more flexible and expressive sound for solo playing than the sound of the instrument normally amplified. Switching and control circuitry enable the musician to return to a conventional amplified tone which would be preferred for rhythm (or chordal) playing.
