Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents the legendary benchmark for enclosed tuners, engineered with precision CNC manufacturing and high-grade brass posts. Featuring an optimized 1:18 gear ratio, it delivers an exceptionally smooth, sensitive, and precise tuning experience with rock-solid stability.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine ensures direct center alignment of the string post via the banjo bolt without requiring stepped headstock drilling. This design eliminates tilting torque and reduces mechanical strain on both the post and rear mounting screw.
Permanently lubricated with Schaller special grease, the M6 180 is entirely maintenance-free and engineered for wear-free performance across diverse playing conditions.
