Introducing the NEW Kluson Revolution G-mount 19:1 high ratio locking tuning machine. Kluson has truly introduced a game changer with the traditional footprint and newly designed sealed die-cast housing. These state of the art tuners are designed to directly retrofit die-cast tuners with a hex head bushing adding a rear knob locking mechanism, traditional Kluson two-screw mounting pattern and modern 25/64 inch peghole. The vintage outline, pearloid plastic keystone button and pin-stripes pay tribute to Kluson heritage while the brand new housing appearance incorporates all the features the modern guitarist demands. High gear ratio guarantees silky smooth operation, fine tuning stability and no backlash all in a sealed one-piece housing that looks like it belongs in a jewelry case! All mounting hardware is included.
