Grover® 3 Per Side Rotomatics With 18:1 Gear Ratio
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.
Please Note: Grover tuning machines produced prior 1985 use different specifications for threading and shaft sizing. Current production replacement parts are not interchangeable on vintage (pre-1985) Grover tuning machines.
