An electronic vibrato system for a stringed instrument comprises an actuator and microcontroller which are disposed within a chassis. The control arm moves the actuator from a resting position to non-resting, rotated positions. The system is below a face of a stringed instrument such that the system has a disposed fulcrum within the instrument. The rotated positions impart resistive forces on said actuator and imparting control signals. The microcontroller processes said control signal and modulates pitch.
