Abstract
A pick-up apparatus for a string instrument comprising an array of supports for positioning an array of detectors, each of which monitors strings' vibrations and generates electrical signals, each of the supports straddling a string of the stringed instrument. The detectors include a sensor mount, a divergent light source, and first and second optical sensors which receive light simultaneously when the light source is illuminated and generates an electrical analog output signal.
