D'Addario Planet Waves NS Micro Clip-Free Tuner & Metronome
The ultimate in discreet tuning, the NS Micro Clip-Free Tuner attaches directly to your instrument's tuning machine (screw included) so your tuner is always at hand and visible to only you! Like the popular clip-on version, it features a full color display and metronome in a discreet housing. Mounts directly into one tuning machine hole; no additional holes needed. Same features as the NS Micro Tuner, calibration from 410-480Hz.
