Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and stability, featuring an improved 1:18 gear ratio for exceptionally smooth and accurate tuning. Originally establishing the worldwide standard for enclosed tuners in 1966, this upgraded design incorporates CNC-machined components and surface finishes that deliver reliable performance.
Engineered with high-grade brass posts precisely fitted into the housing, the M6 Pin ensures maximum tuning stability and wear resistance. Each enclosed unit is permanently lubricated with Schaller special grease, providing a completely maintenance-free operation over its lifespan.
Installation is streamlined via the innovative stepped M6 flanged washer, which centers the string post securely through the threaded bushing without requiring stepped headstock holes. This design eliminates tilting torque and reduces mechanical stress on both the post and mounting hardware.
