Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an upgraded 1:18 gear ratio. Designed with CNC-machined components and a self-locking drive mechanism, it provides smooth, velvety adjustments and unmatched tuning stability for demanding players.
Equipped with high-grade brass string posts precisely fitted to the housing, each tuner ensures wear-free longevity. The innovative stepped M6 flanged washer centers the post reliably via the threaded bushing, eliminating tilt moment and eliminating the need for stepped headstock drilling.
Featuring permanently lubricated internal gearing with Schaller special grease, these maintenance-free tuning machines retain the identical installation dimensions of previous models, making direct replacement quick and hassle-free.
