Designed specifically for acoustic guitar, ukulele, and other
acoustic instruments, the D'Addario chromatic 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!
