Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth tuning performance with its refined 1:18 gear ratio. All components are CNC-machined to exact tolerances and surface-finished, featuring a self-locking drive mechanism for stable, reliable operation.
Equipped with high-grade brass string posts engineered for wear-free performance, the M6 180 provides maximum tuning stability. Each closed-type unit comes permanently lubricated with Schaller special grease for completely maintenance-free functionality.
The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt without requiring stepped peghead holes. This design eliminates tilting torque and relieves mechanical stress from both the post and the rear mounting screw.
