Standard guitar-style worm and gear tuners, used on most ukuleles today, were designed for high-tension steel strings and respond slowly and inefficiently to a uke’s short scaled, nylon strings. The gear ratios on most ukuleles is 16:1 or higher. (Meaning it takes 16 full turns of the button to rotate the post 360 degrees) No wonder ukuleles are hard to tune! Plus, there is the weight issue with standard tuners, making ukuleles headstock heavy. The Graph Tech team decided to tackle these problems that have plagued uke players world-wide and created a new patent-pending technology that makes ukulele tuning and staying in tune a breeze!
