Planet Waves NS Micro Tuner
This neat little electronic tuner fits very snugly on flat head instruments. It can be mounted on the front or back of the head stock and the muli-color display can by reverse for easier viewing. It has an easy to use ratchet clamp and a visual metronome. The calibration range is 410 to 480 Hz. When tuning, the display will turn green on the note you are tuning to.
