A Kyser Quick-Change is cleverly designed and built to last. It's reliable and does exactly what it's designed to do: clearly raise the guitar's pitch so you can play on a different fretboard without retuning or changing fingering. Seasoned professionals and beginners alike appreciate the way Kyser Quick-Change helps them transpose their guitar in seconds, with just one hand. The beauty of the Kyser Quick-Change lies in its simplicity. We pioneered the design, and although often imitated, a Kyser is never equaled. There's no substitute for a Kyser Quick-Change.
