The neck on your classical guitar is different than regular acoustic guitars. It has a flat fret board which requires a capo with no radius. The Kyser® Quick-Change™ for classical guitars does not have a radius and is specifically manufactured with just the right amount of tension for classical strings. This Kyser® Quick-Change™ is expertly engineered and built to last. It is reliable and does just what it is designed to do — clearly raise the pitch of the classical guitar so you can play in a different key without retuning or changing fingering. Seasoned professionals and beginning players alike appreciate how the Kyser® Quick-Change™ helps them transpose their classical guitar in seconds, with only one hand. The beauty of the Kyser® Quick-Change™ is in its simplicity. We pioneered this design and although often imitated, a Kyser® is never equaled. There is no substitute for a Kyser® Quick-Change™.
