Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning precision and velvety-smooth operation with its refined 1:18 gear ratio. Continuing the legacy of the original closed-type tuner introduced in 1966, this model features high-precision CNC-machined components and high-grade brass string posts engineered for maximum tuning stability and wear resistance.
Equipped with an innovative stepped M6 flanged washer, this tuning machine reliably centers the string post through 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 performance.
Each closed-type unit is permanently lubricated with proprietary Schaller special grease for completely maintenance-free operation. The self-locking drive mechanism guarantees steady, sensitive adjustments suitable for premium guitar builds and direct replacements.
