Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine features a precise 1:18 gear ratio that delivers smooth, reliable tuning stability and exceptional accuracy. All structural parts are precision CNC-machined and surface-treated, utilizing a self-locking drive mechanism to maintain pitch under performance conditions.
Crafted with premium brass posts fitted directly into the sealed housing, this tuner minimizes mechanical wear and ensures lifelong durability. The closed housing design is permanently lubricated with Schaller specialized grease, rendering the unit completely maintenance-free.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post through the banjo bolt without requiring stepped headstock drilling. This design absorbs tension, eliminates tilting torque, and safeguards headstock mounting integrity.
