GROVER ORIG. LOCKING ROTOMATICS ® BLACK CHROME SET 6 3+3

Grover Locking Rotomatics ® give you the ease of use provided by a standard tuner and the positive locking of our internal cam post. Simply insert the string through the string hole, pull to tension by hand and begin tuning. As you start to tune, only the locking cam in the string post turns. Once the string is locked, the string post begins to turn allowing you to bring the string to pitch. In less then one revolution of the string post, you will be in tune, to stay in tune. Gear ratio is 18:1.
