Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 tuning machine delivers unmatched precision and smooth tuning comfort with an optimized 1:18 gear ratio. As the modern evolution of the legendary original closed-housing tuner introduced in 1966, it features extensive CNC-machined refinements and high-grade brass posts engineered for maximum tuning stability and wear resistance.
Equipped with Schaller's innovative stepped flanged washer, the tuner centers securely via the banjo bolt without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical stress on both the string post and rear mounting screw, ensuring reliable, long-term performance.
Permanently lubricated with Schaller special grease, these fully enclosed tuners are entirely maintenance-free. Their self-locking drive mechanism guarantees uniform, sensitive, and stable tuning across all playing conditions.
