Detail 01
19:1 gear ratio
Supports fine, controlled pitch adjustments at each tuning peg.

Independent shopping perspective
For a guitar with six-in-line vintage Kluson tuners and a hex bushing, these nickel locking Revolution H-Mount machines offer a direct retrofit path. Their 19:1 ratio is intended for controlled, accurate pitch setting, and the sealed die-cast housing encloses the mechanism. Staggered post heights eliminate the need for a traditional string tree. Oval buttons, a slim outline, and pinstripes keep the visual direction rooted in classic Kluson styling, with mounting hardware included for installation.
