Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers high-precision tuning for guitars, featuring a 1:18 gear ratio that ensures smooth and accurate adjustment. Built with precision CNC-machined components and high-grade brass string posts, this closed-gear design guarantees exceptional tuning stability and long-lasting performance.
Equipped with an innovative stepped M6 flanged washer, the system centers the string post securely through the threaded bushing without requiring stepped headstock drilling. This smart design eliminates tilting torque and reduces mechanical stress on both the post and rear mounting screws.
Each unit is permanently lubricated with Schaller special grease for completely maintenance-free operation. Engineered for direct replacement of legacy units, it offers a seamless upgrade for instruments requiring superior reliability and tuning comfort.
