The tiny design and reversible screen allow the tuner to hide effortlessly behind or mount on the front side of the headstock, while permitting the tuner to remain clamped to the instrument inside most cases when stored. A 360 degree swivel mechanism and adjustable padded clamp offers optimal viewing angles and maximum positioning flexibility. As a result, the Planet Waves NS Mini Tuner is equally at home on left and right-handed instruments as well as on small and large headstocks, making it the ideal choice for the widest variety of players and instruments. The NS Mini Headstock Tuner also features an easy-to-read color changing backlit display which is powered by a readily available CR2032 battery (included). Maximum battery life is provided by the auto-off function, shutting the tuner off automatically after several minutes of no signal. Enjoy effortless and inconspicuous tuning at a great value with the NS Mini Headstock Tuner. Designed in Conjunction with Ned Steinberger
