Grover® 3 Per Side Or 6 In Line Mini Locking Rotomatics

The same innovative engineering and classic design as the Original Locking Rotomatics®, but with smaller buttons for 6-in-line guitars, or for those who prefer a little more space for their fingers. Gear ratio is 18:1.

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.
