Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. Continuing the legacy of the original 1966 closed-housing design, this updated model integrates modern innovations while preserving its renowned reliability and aesthetic appeal.
Precision CNC-machined components and high-grade brass string posts ensure velvet-smooth operation, exceptional wear resistance, and long-term tuning stability. The closed housing is permanently lubricated with Schaller special grease for completely maintenance-free performance.
Equipped with an innovative stepped flanged washer with a 0.39-inch diameter base, the M6 135 centers the string post perfectly through the banjo bolt without requiring stepped headstock drilling. This design eliminates tilting torque and reduces physical strain on the post and mounting screws.
