Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth tuning stability with an upgraded 1:18 gear ratio. All components are CNC-machined and surface-treated, featuring a self-locking drive mechanism that guarantees consistent, sensitive, and stable operation.
Crafted with premium brass string posts precisely fitted into the housing, this tuning machine provides maximum wear resistance and tuning accuracy. Permanent lubrication with Schaller special grease ensures completely maintenance-free performance throughout its lifespan.
The innovative stepped M6 flanged washer reliably centers the string post via the threaded bushing, eliminating the need for a stepped hole in the headstock. This design removes tilting torque and relieves pressure from both the post and the rear mounting screw.
