The Planet Waves Headstock Tuner allows you to tune easily and accurately in noisy and dimly-lit environments where many other tuners fail. The design of the tuner permits the highly sensitive piezo to sit horizontal to the vibrating surface of the instrument allowing the most direct and strongest transference of signal from the instrument to the tuner for greater accuracy. The easy to read display can be seen in any lighting condition and provides the perfect viewing angle for the performer while the compact design blends right in with the instruments aesthetics so you can leave it on your entire performance. Planet Waves electronic tuners are designed by musicians for musicians featuring intuitive features, easy to read display"s and tuning accuracy.
