Tuning Machines

Machine heads without a sealed gear are criticized for not having the same smooth performance, efficiency and durability that sealed gear tuners have. The SD series solves these problems by combining "Rock-solid" technology and the post collar or: "Self-Center Guide", found on enclosed gears in the base plate of the gear allowing the post to perfectly align itself with the bushing which attaches the gear to the headstock. The SD series uses a torque balancer to ensure steady rotation of the tuner button giving high quality sound performance as well as great functionality. Through its use of the ideal materials selected for each component part you also obtain a far superior sound. These are 3+3 (Three on a side) configuration. Mounting hardware included. 1:15 gear ratio.

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.
