Grover 305C 3 Per Side Mid-Size Rotomatics

The Mid-Size series is made with the same quality as the other Rotomatic® models. Slightly larger than the Mini Rotomatics®, the mid-size series features an 18:1 gear ratio for smoother, more precise tuning. This compact machine head is perfect for use on smaller and in-line headpieces.

Please Note: Grover tuning machines produced prior to 1985 use different specifications for threading and shaft sizing. Current production replacement parts are not interchangeable on vintage (pre-1985) Grover tuning machines.
