Snark ST-8 features flat tuning, transpose functions, and easy pitch calibration. Its ultra-tight tuning reacts directly to the vibration of your instrument, so you never have to worry about background noise as you tune. Just clip the Snark ST-8 to the headstock of your guitar or any resonant part of your instrument, and you’re good to go. What’s more, the Snark ST-8’s upgraded high-definition display rotates 360 degrees, so it’s perfect for lefties too!
