Daddario Planet Waves NS Pro Ukulele Capo. Designed specifically for Ukuleles, the NS Ukulele Capo pro assures buzz free, in tune performance at any fret. A micrometer adjustment mechanism allows for exact tension without excessive force in any position on the neck and greatly reduces the need for re-tuning during and after capo use. The sleek aircraft grade aluminium construction adds negligible additional weight to the instrument or obstruction to the hand. Amazingly elegant, reliable and user friendly.
