Grover 102-18N Rotomatic Tuners 3 +3 Nickel Finish

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 18:1. 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.

Same as 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 Rotomatics® uses the exact housing as the original. Only the gearing has changed. Includes washers, bushings, and wood screws.
