Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with its refined 1:18 gear ratio. Designed as an evolution of the legendary original sealed tuner, it features CNC-machined components and high-grade brass posts engineered for maximum stability and wear-free performance.
Equipped with an innovative stepped flanged washer, this tuner simplifies installation and maintains solid string post alignment through the hex screw without requiring stepped peghead drilling. This design eliminates tilting moment and reduces mechanical stress on the mounting components and string post.
Permanently lubricated with Schaller special grease for maintenance-free reliability, the self-locking drive ensures stable, sensitive, and uniform adjustments. Its streamlined housing profile offers a direct, hassle-free replacement for previous M6 iterations.
