Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin Guitar Tuning Machine sets an industry standard with its refined 1:18 gear ratio, delivering precision tuning and stability. Designed with high-precision CNC-machined parts and a self-locking drive, this tuning machine ensures consistent, sensitive, and reliable adjustments for modern musicians.
Featuring high-grade brass posts fitted into a durable housing, this unit ensures wear-free longevity and exceptional tuning integrity. The innovative stepped M6 flanged washer centers the string post securely via the banjo bolt, eliminating tilting friction and removing the necessity for stepped headstock boreholes.
Permanently lubricated with Schaller special grease, the sealed housing provides completely maintenance-free operation over its lifespan. The two-pin configuration offers a standardized 0.39-inch (10 mm) pin spacing for seamless integration and robust mounting.
