Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio for ultra-smooth and accurate tuning. Building on the legendary closed-housing design established in 1966, this model delivers unmatched tuning comfort, exceptional stability, and seamless performance.
Every component is CNC-machined to exacting tolerances and features premium surface finishes. The high-grade brass posts fit precisely into the housing to prevent wear, while the self-locking drive and permanent lubrication with specialized grease ensure completely maintenance-free operation.
Equipped with an innovative stepped flanged washer, the tuning machine centers the string post effortlessly via the hollow bolt without requiring a stepped headstock hole. This mechanism eliminates tilting torque and protects mounting screws, making installation straightforward and reliable.
