Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine series delivers exceptional precision and tuning comfort with an upgraded 1:18 gear ratio. Continuing the legacy of the original 1966 closed-housing design, these precision-engineered tuners feature state-of-the-art enhancements for uncompromising performance.
Crafted with CNC-machined components and solid brass string posts fitted directly into the housing, each unit ensures exceptional tuning stability, smooth operation, and wear-free longevity. The self-locking drive and Schaller special grease lubrication guarantee smooth, maintenance-free functionality.
Installation is streamlined via the stepped M6 collar washer, which centers the string post precisely through the hollow screw without requiring stepped headstock boreholes. This design eliminates tilting torque and protects mounting hardware from unnecessary tension.
