Tuning Machines

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.

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.

The same innovative engineering and classic design as the Original Locking Rotomatics®, but with smaller buttons for those who prefer a little more space for their fingers. Gear ratio is 18:1.
Contains 3 treble and 3 bass

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. Insert the string through the post hole, wrap around once, then lock by tightening with the thumb screw. Perfect replacement for the most standard machine heads. Includes all mounting hardware. Includes 3 treble and 3 bass.

The Original Grover® Sta-Tite™ machine head now available with an 18:1 gear ratio for more precise tuning. With the classic styling and butter bean button of the original Grover® Sta-Tite™ machine heads, these tuners offer the stability of a modern tuner with the vintage look of the originals. Original Sta-Tite™ tuners can be found on countless classic guitars from Martin, Guild, and others dating as far back as the early 1900's. Wood screws included - no bushings required.

The same excellent features as the original 97 series, now with an 18:1 gear ratio!
