The Snark ST-2 fully chromatic tuner is a new and improved version of the Snark SN-2 All-Instrument Tuner. It is great when you need to tune more than just guitar and bass. This compact tuner also works with mandolins, banjos, violas, ukuleles, flugelhorns and many more. 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. 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.
