Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. All components are CNC-machined to exact tolerances and permanently lubricated with Schaller special grease, ensuring maintenance-free and stable performance.
Featuring high-grade brass posts fitted precisely into the housing, this tuning machine provides excellent wear resistance and tuning stability. The stepped M6 flanged washer centers the string post securely over the threaded bushing, eliminating tilt and removing stress from both the post and mounting screw.
Designed to match the mounting dimensions of its historic predecessor, the M6 135 allows for seamless, direct replacement without headstock modifications. It provides smooth operation and self-locking drive mechanics for discerning guitarists seeking premium hardware.
