Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers precision and tuning comfort with its refined 1:18 gear ratio. Engineered for sealed operation, it continues the legacy of the original M6 with modern enhancements designed for consistent and stable performance.
Each component is CNC-machined and surface-treated, featuring high-grade brass string posts and permanently lubricated internal gearing using Schaller specialty grease for maintenance-free reliability.
The innovative stepped M6 flanged washer ensures self-centering installation over the threaded bushing, eliminating tilting torque and reducing strain on mounting hardware without requiring stepped headstock boreholes.
