PRODUCT DESCRIPTION
- This full set of four Graph Tech PRU-4004-BK Ratio Tune-A-Lele ukulele machine heads are not only the lightest in the world, but feature a 6:1 gear ratio, bringing the tension right down compared to the standard 14:1 to 16:1 ratio of standard guitar machine heads and setting them up for all ukulele models. Once installed, these heads ensure quick and smooth tweaking as well as boosted tuning stability and, because they weigh just 5 grams each (compared to the 25 grams of a standard machine head), the balance of your instrument remains unaffected. These machine heads are easily mounted using the included pack of screws.
