Distinctive in styling and quality, the Imperial™ made its 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.
