The original Rotomatic® with an improved higher ratio gearing. The 18:1 ratio provides for finer tuning and greater stability. The finer gears provide smoother tuning and a higher degree of backlash elimination. This new version of the Rotomatic® uses the exact housing as the original. Only the gearing has changed. Includes washers, bushing and wood screws.

These guitar machines are a triumph in engineering and styling. The housing provides a maximum bearing for worm, gear and string post. Gear ratio is 14:1. Worm and gear are precision-cut for perfect meshing. This eliminates backlash and slippage. Countersunk tension screw permits player to regulate turning tension to any degree. Gear box has a special lubricant for lifetime, trouble-free service. Includes 5/8” washers, bushings and wood screws.

The introduction of the new Grover Locking Rotomatics® gives 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 than one revolution of the string post, you will be in tune, to stay in tune. Gear ratio is 18 to 1.
