With more strings, you need more tension and a larger body than the original Kyser® Quick-Change®. This Kyser® Quick-Change® is specifically designed for your 12-string guitar and is built to last. It is reliable and does just what it is designed to do — clearly raise the pitch of the 12-string 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 12-string 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®.
