The Planet Waves Dual Capo Tuner combines the widely acclaimed NS Dual Action Capo with a Planet Waves precision chromatic tuner. The first of its kind, the NS Capo Tuner provides accurate tuning at any fret or when clipped on the headstock of your acoustic or electric guitar. The patented compound action of the Dual Action Capo reduces the force necessary to open and close the capo. It also eliminates side pulling the strings out of tune, a common issue with standard trigger-type capos. Lightweight, accurate and easy to use, simply adjust the micrometer tension knob just enough to eliminate string buzzing and enjoy repeatable in-tune performance at every fret.
