Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents the continuous evolution of a legendary design, featuring an upgraded 1:18 gear ratio for exceptionally smooth and precise tuning accuracy. Built with high-precision CNC-machined components and high-grade brass posts, these tuners deliver long-term tuning stability and wear-free operation.
Equipped with an innovative stepped M6 flanged washer, the unit ensures effortless installation and solid centering of the string post without requiring a stepped peghead bore. This advanced construction eliminates tilting torque and reduces mechanical stress on both the tuner post and the rear mounting screw.
Every sealed housing is permanently lubricated with specialized grease for completely maintenance-free performance throughout its lifespan. Engineered to replace previous M6 generations without modification, it offers seamless integration for modern guitar builds and upgrades alike.
