The newest addition to the Grover family, these locking machine heads utilize the famous 18:1 Rotomatic® design with a “thumb screw” mechanism which locks the string into place.

Distinctive in styling and quality, the Imperial made it's first appearance in the 1970s. The most notable feature of this unique machine head is the futuristic Three Step button, a fresh and funky design trademarked by Grover. This re-introduction of the Imperial is an exact reproduction of the originals, including a 16:1 gear ratio.
This model offers the same specs and styling as the Original “Milk Bottle" style 102 Series, but with Pearloid Buttons and button retainer. 18:1 ratio.
The introduction of the new Grover Locking Rotomatics® gives you the ease of use provided by a standard tuner and the positive locking of our internal cam post. Simply insert the string through the string hole, pull to tension by hand and begin tuning. As you start to tune, only the locking cam in the string post turns. Once the string is locked, the string post begins to turn allowing you to bring the string to pitch. In less than one revolution of the string post, you will be in tune, to stay in tune. Gear ratio is 18 to 1.
These guitar machines are a triumph in engineering and styling. The housing provides a maximum bearing for worm, gear and string post. Gear ratio is 14:1. Worm and gear are precision-cut for perfect meshing. This eliminates backlash and slippage. Countersunk tension screw permits player to regulate turning tension to any degree. Gear box has a special lubricant for lifetime, trouble-free service. Includes ⅝" washers, bushings and wood screws.

Includes washers, bushing and wood screws.
