The USB rechargeable version of the D'Addario Equinox Headstock Tuner precisely tunes guitars, basses and other stringed instruments utilizing vibrations rather than sound.
Using a highly sensitive piezo sensor and large multi-color display, the USB Rechargeable Equinox Headstock Tuner allows you to tune easily and accurately in noisy and dimly lit environments where many other tuners fail. The tuner features a pivoting display and Micro USB port for charging.
D’Addario's innovative tuner designs feature intuitive interfaces, easy-to-read displays, and provide exceptional tuning accuracy.
