Description
Grover took the original Rotomatic
tuner and refined it with a higher 18:1 gear ratio, giving players finer pitch control and more stable tuning at the peg. The housing itself hasn’t changed a bit — it’s the same trusted Rotomatic body players have relied on for years. What’s different is the gearing inside: tighter, smoother gears that cut down on backlash and make small adjustments easier to dial in accurately.
- 18:1 gear ratio for precise, stable tuning
- Same housing design as the original Rotomatic
- Smoother gear engagement with reduced backlash
- Gold finish
- Set of 6 tuners (3 treble, 3 bass) for standard guitars
- Includes washers, bushings, and wood screws
Model 102-18G is built for standard 6-in-line-per-side headstocks and drops in as a straightforward hardware upgrade. If your current tuners feel loose or imprecise, this set brings tighter mechanical feel without changing the look or footprint of a classic Rotomatic setup.
