Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning precision and stability, featuring an improved 1:18 gear ratio for smooth and delicate adjustment. Built upon the legacy of the original 1966 closed-housing design, this modernized version incorporates refined CNC-milled parts and a self-locking drive.
Crafted with premium brass posts precisely fitted into the housing, the M6 180 ensures maximum wear resistance and consistent performance. Every closed unit is permanently lubricated with Schaller special grease, providing an entirely maintenance-free operational life.
The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt without requiring stepped peghead drilling. This structural improvement eliminates tilting torque and relieves mechanical stress from both the post and mounting screws.
