Guild Clip-On Digital Tuner Black

Powerful tuning in a small package. Even in the noisiest settings, this unobtrusive digital tuner will detect a pitch through its vibration sensitive clip.
Extended Battery Life: Unlike other digital tuners, the power switch is built into the clip to conserve battery life. As soon as you clip it onto the instrument, the tuner comes to life. It turns off when removed or automatically after 5 minutes of being attached.
Suitable for Many Instruments: This chromatic tuner will work great on any instrument including guitar, bass, ukulele, violin, or any instrument you can clip it to!
