Sustainer device for electric guitar or bass - has pick=up coil for detecting string oscillation, and coil for exciting string to oscillate using amplified signal from pick=up

摘要

The electric guitar sustainer device produces a lasting sustain as well as feedback effects. Each string is provided with a magnetic pick up coil for converting the string's oscillation into a voltage signal. A multichannel amplifier amplifies the signal for each respective string and feeds it back to a coil located near to the string, which excites the string to continue oscillating. By controlling the gain of the amplifier, the desired effect can be selected. ADVANTAGE - 'Pure' sound
