The convenience of a clip-on tuner with rock-solid Sabine tuning algorithm.
The Zoid Clip-On Tuner is an amazingly simple chromatic tuner that'll get your guitar, bass, or other stringed instrument in tune in no time. Just clip it on to your instrument, and the Zoid displays the note you play. The bright, two-color LCD display with its high-resolution needle and big note indicator tells you exactly what note you are playing and if you are flat or sharp with a ±50 cent indication. If the LCD fires bright green, you are in-tune. If you are in the red, the needle lets you know if you're flat or sharp. With the Zoid tuner, you can either tune using the clip that transfers the note directly to the tuner—great for noisy rooms—or tune with the built-in mic if you want to tune up several instruments at once. It has a 7-octave tuning range for a wide variety of instruments, with a 3-minute auto-shutoff when it receives no signal.
This professional instrument tuner is backed by Sabine's 2-year warranty.
