This all-instrument vibration sensing tuner contains a redesigned processing chip and pitch calibration for accurate tuning of any instrument... 1/10th of 1 Hz Accuracy! It features a brighter display and 360 swivel head allow tuning at all angles, with gripped clip grabs to ensure the tuner is tight and stays in place. The ST-8 also includes a tap tempo metronome!

SNARK advises NOT to use its tuner with any instruments having these types of finishes: Nitrocellulose Lacquer, Polyurethane, French Polish, Oil Finish or Gibson® guitars which have nitrocellulose finishes, unless you accept the risk of dents to the headstock.”
