The Snark ST-2 chromatic tuner is great when you need to tune more than just guitar and bass. This compact tuner also works with mandolins, banjos, violas, ukuleles, flugelhorns - you name it! Tune from a distance, by virtue of the ST-2's built-in microphone. Even if it's clipped to your music stand a few feet away, the ST-2's upgraded high-definition display is easy to read. The ST-2 is one of the most versatile compact tuners you'll find at Sweetwater. Flat tuning, transpose functions, and easy pitch calibration provide more tuning options than most chromatic tuners. Boasting more accuracy than ever, the Snark ST-2 also doubles as a tap tempo metronome.
