Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers exceptional precision and tuning comfort with an advanced 1:18 gear ratio. Continuing the legacy of the original closed-gear standard set in 1966, this model incorporates CNC-machined components and surface finishes for smooth, velvet-like tuning performance.
Equipped with high-grade brass posts precisely fitted into the housing, the M6 135 delivers maximum tuning stability and wear-free operation. The self-locking drive mechanism ensures consistent tension and sensitive adjustments across all string setups.
Featuring the innovative stepped M6 flanged washer, this tuning machine centers the string post securely through the hollow screw without requiring stepped headstock drilling. Permanently lubricated with Schaller special grease, each closed-housing tuner is completely maintenance-free and matches the exact mounting dimensions of previous iterations for seamless replacement.
