Supreme Series Tuning Machines 3 Per Side An 18:1 gear ratio in the traditional stamped steel housing. The housing bears the series name “SUPREME” in place of the original “DELUXE” moniker. Using all vintage specifications aside from the gear ratio, these tuning machines require no modification for vintage instruments. Available with single ring keystone buttons. Includes all hardware needed for installation

**Important these require an 8.8mm hole in the headstock to work. If you have a nut and washer securing the tuner from the front you will need a set of gold adapter bushings. I sell them in my store.
