Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents high-precision engineering and enduring reliability. Built with a refined 1:18 gear ratio, it delivers velvety-smooth, highly accurate tuning response. Precision CNC-machined components and high-grade brass string posts ensure superior tuning stability and wear-free operation.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post without requiring a stepped headstock bore. This design eliminates tilting torque and reduces mechanical stress on both the post and the rear mounting screw. Sealed internal components are permanently lubricated with Schaller special grease for completely maintenance-free performance.
Engineered for seamless direct replacement of previous generation models, the M6 180 installs effortlessly without modifications. Each component is finished to exacting standards, offering smooth torque and exceptional long-term stability for demanding musicians.
