Planet Waves PW-CT-12 D'Addario NS Micro Clip-On Tuner THE STEALTH TUNER  Your audience will never know there is a tuner on your instrument with the highly precise Micro Clip-On Tuner. The lightweight, discrete, compact tuner hides behind the headstock practically blending into the instrument and is small enough to be kept on your instrument while stored in its case. At 1.25, you will want one for each stringed instrument you own. EXTREME ACCURACY  The NS Micro features an extremely accurate piezo transducer that picks up an instruments vibration rather than sound. A wide calibration range (410-480Hz) guarantees precise performance and a visual metronome mode (20-270bpm) adds an additional practice tool. EASY TO READ - The easy-to-read, tri-color backlit screen displays the note in red when out of tune, yellow when close, and green when in tune. Powered by a readily available (and included) CR2032 battery, you will enjoy maximum battery life thanks to the tuners auto-off function. VERSATILE - Featuring a 360-degree swivel mechanism and adjustable padded clamp, the NS Mini offers optimal viewing angles and maximum positioning flexibility. For left or right-handed instruments with small or large headstocks, it is the ideal choice for acoustic and electric guitars, basses, mandolins, banjos and ukuleles.
