BOSS TU-02 Clip-On Tuner

The TU-02 Clip-On Tuner from BOSS tunes a variety of instruments with its versatile modes and quick-change design. The easy-to-use tuner features modes for guitar, 4- and 5-string bass and ukulele, as well as chromatic mode for alternate tunings and other stringed instruments. The clip-on tuner supports flat tuning over a range of two semitones and is great for players who like to tune low for a heavier sound. With adjustable calibration from 430Hz to 450Hz, the tuner can be set to a reference other than the default 440Hz standard if needed.
