Grover GR102N 3+3 Rotomatic Guitar Tuner Machine Heads
- 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.
