A 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 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 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.
