Kluson Revolution E-Mount 3-Per-Side Non-Locking Tuning Machines, Chrome

Upgrade a compatible electric or acoustic guitar with this chrome Kluson Revolution E-Mount tuning-machine set. The 20:1 gear ratio provides fine tuning adjustment, with three tuners per side for a six-string, 3+3 headstock layout.

This is the non-locking E-Mount version. It uses 10 mm pegholes, screw-in bushings and washers, and a single mounting screw positioned at 6 o'clock low. Designed for many instruments manufactured after 1970, but not a universal drop-in replacement: compare your existing peghole size, screw position, and headstock clearance before ordering.
