Grover® 3 Per Side Imperial

Distinctive in styling and quality, the Imperial™ made it's first appearance in the 1970's. 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.

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.
