Patent ID: 7968778

Claim:
A combination capo and tuner, comprising a capo connectable to the neck or headstock of a stringed instrument with sufficient contact to mechanically transmit a spectrum of mechanical vibrations commensurate with the acoustic vibration of a string; and a tuner mechanically integrated with the capo and including a sensor such that mechanical vibrations transmitted through the capo are received by the sensor, and a tuning display system coupled to the sensor that displays a tuning figure of merit commensurate with the acoustic vibration of the string wherein, the capo has a top jaw, spaced apart from a bottom jaw, and an actuator for selectively moving the jaws closer and farther apart, thereby securing the capo on and releasing the capo from the neck or headstock; at least one of the jaws is supported on a rigid shank; and the shank engages the tuner.
