Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning precision and stability with its refined 1:18 gear ratio. Premium CNC-machined components and self-locking drive mechanisms provide smooth, delicate, and consistent performance for discerning musicians.
Crafted with high-grade brass posts precisely fitted into closed housings, each unit is permanently lubricated with Schaller special grease for maintenance-free operation. The stepped M6 flanged collar reliably centers the string post via the banjo bolt, preventing tilt without requiring stepped headstock drilling.
Designed for straightforward replacement without modifications, the M6 180 continues the legacy of precision engineering established by the original closed tuning machine standard.
