Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an upgraded 1:18 gear ratio. Continuing the legacy of the original 1966 closed-housing design, this edition features CNC-machined components and durable brass string posts fitted for smooth, self-locking performance and maximum tuning stability.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine reliably centers the string post through the banjo bolt without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical stress on both the shaft and the rear mounting screw.
Permanently lubricated with specialized grease for maintenance-free operation, the M6 135 retains the exact installation dimensions of its predecessor for hassle-free direct replacement on compatible instruments.
