Secure and Reliable
The TU-02’s high-contrast color display provides accurate, easy-to-view tuning everywhere you play. The rugged, padded clip securely grips to your instrument’s headstock, while swivel adjustment lets you position the display for the optimum viewing angle. A single CR2032 lithium battery provides continuous runtime up to 24 hours, and an auto power off feature conserves battery life when the tuner is idle.
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-02. 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 two semitones down is supported, perfect for players who like to tune low for a heavier sound. And with adjustable calibration from 430 to 450 Hz, you can set the tuner to a reference other than the default 440 Hz standard if needed.
