Rechargeable Battery

A built-in rechargeable battery provides up to 10 hours of continuous runtime, and there’s an auto power off feature that kicks in when the tuner’s not active to conserve battery life. With the included cable, you can charge the TU-05 with the same USB adaptor you use with your phone or tablet.

TU-05

Works with Guitar, Bass, Ukulele, and More

With its versatile modes and quick-change design, you can tune a variety of instruments with the TU-05. Choose from standard tuning modes for guitar, 4- and 5-string bass, and ukulele, or chromatic mode for alternate tunings and other stringed instruments. Flat tuning over a range of three semitones down is supported, perfect for players who like to tune low for a heavier sound. And with adjustable calibration from 431 to 449 Hz, you can set the tuner to a reference other than the default 440 Hz standard if needed.
