Micro D'Addario Clip-On Tuner Designed in collaboration with Ned Steinberger, the D'Addario NS Micro clamp tuner precisely tunes a wide variety of stringed instruments. It is very compact, light and easy to use. The highly sensitive piezoelectric mic and backlit display allow very precise tuning even in loud, dark or brightly lit environments where other tuners are not working. The compact design allows the tuner to hide behind the head of the guitar effortlessly, hiding from your audience and allowing it to stay on the instrument inside most protective covers. Featuring a 360-degree swivel mechanism and an adjustable padded clamp, the NS Micro offers optimal viewing angles and positioning flexibility. As a result, the NS Mini is equally suited to use by left-handed as well as right-handed, and on instruments with small and large heads, making it the ideal choice for the widest variety of musicians and instruments, from 5-string bass on Ukulele. The NS Micro also features an easy-to-read color-changing backlit display, which is easily seen in dark scenes or in direct sunlight. Maximum battery life is ensured by the auto-off function, which automatically turns off the tuner after a few minutes to preserve the life of the CR2032 battery (included). Complemented with the latest and more precise version of D'Addario software, the NS Micro also offers adjustable calibration between 430 Hz and 450 Hz for use in a wide variety of gaming situations. Enjoy easy and precise adjustments with discretion! D'Addario electronic tuners are designed by musicians for musicians, having as a feature ease of use combined with high tuning precision.
