Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth operation with an advanced 1:18 gear ratio. All components are CNC-machined to exact tolerances and surface-finished to ensure consistent, highly sensitive, and stable tuning.
Equipped with high-grade brass string posts engineered precisely into the housing, this tuning machine provides maximum wear resistance and tuning stability. The closed housing design is permanently lubricated with specialized grease for completely maintenance-free performance.
An innovative stepped flanged washer reliably centers the string post without requiring stepped headstock drilling, effectively eliminating tilting torque and reducing strain on mounting screws.
