Also used on the Epiphone Casino and current Epiphone production of Les Paul and SG 400 models. This model Kluson tuning machine is also a direct replacement for all current re-issue 50's and 60's Gibson production and other series that utilize a vintage style individual tuning machine. These are six individual tuners, 3 per side(not on a plate). All hardware including bushings and mounting screws are included in the set.
