These are Grover's Mini-locking Rotomatic tuners (406 series) - the same innovative engineering and classic design as the original Grover Rotomatics except with reduced housing size and buttons.

These typically are designed for usage on instruments with 6-in-line tuning machine formats where spacing is limited or more clearance between tuning machines is desired.  Gear Ratio = 18:1 Requires a .391 hole size (25/64 drill).

Grover's patented locking mini-tuners have eliminated the obstacles of other locking devices.  Since there are no external mechanisms to initiate the locking action, the machine head's appearance is like any other.
