ABSTRACT:
In a first embodiment, a columnated light beam is transmitted to a lens aperture of continuously variable size. The lens aperture is coupled to the tremolo arm of a solid body electric guitar. Light from the lens aperture is focussed upon a photosensitive surface of a photo-transistor. The photo-transistor provides a tremolo voltage that is an analog of the position of the tremolo arm. In a second embodiment, a potentiometer has its shaft coupled to the tremolo arm. The wiper arm of the potentiometer provides the tremolo voltage.
