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 â€” 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. Griffin pioneered this design and although often imitated, a Kyser is never equaled. There is no substitute for a Kyser Quick-Change. Highly recommended by players at Axe 'N Gear Music.
