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.
