D'Addario NS Micro Sound Hole Tuner

Designed specifically for acoustic guitar, ukulele, and other acoustic instruments, the chromatic NS Micro Soundhole Tuner remains perfectly concealed within the instrument's soundhole for discreet tuning. The non-marring universal mounting clip allows stress-free installation, while the highly sensitive piezo transducer senses vibrations directly from the soundboard for fast and accurate tuning response. The bright, multi-color display allows easy viewing in any environment. It's so small, convenient, and accurate, you'll want one for every acoustic instrument you own!
