Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers refined tuning precision and velvety-smooth operation through an advanced 1:18 gear ratio. Engineered as the modern evolution of the legendary original closed tuner, it combines high-performance mechanics with enduring stability.
Every component is CNC-machined to precise tolerances and surface-finished, featuring self-locking gearing alongside high-grade brass string posts accurately fitted to the housing. Premium internal components are permanently lubricated with Schaller special grease for entirely maintenance-free reliability.
Installation is streamlined via the innovative stepped M6 flanged washer, which centers the string post securely over the banjo bolt without requiring a stepped headstock hole. This design eliminates tilting torque and effectively relieves stress on both the post and the rear mounting screws.
