Mid-Size 6-In-Line Locking, Single Pin
Designed for stability, accuracy and rigidity, our True Lok mid-sized 6-in-line locking tuning keys feature staggered posts that eliminate the need for a string guide, an 18:1 gear ratio for more accurate tuning, and an easy-to-use lock wheel on the back of the key that offer better tuning stability as well as making string changes quick and easy.  Designed to be a more compact tuner that's better suited for smaller headstocks and with a single pin format to anchor the key in place instead of a screw, these keys offer a sleek, modern look that would complement any guitar!
