Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine delivers state-of-the-art precision and exceptional tuning stability. Featuring an upgraded 1:18 gear ratio, it ensures an ultra-smooth, delicate, and highly accurate tuning experience for all playing styles.
Every component is CNC-machined to exact tolerances and permanently lubricated with Schaller special grease, providing completely maintenance-free, self-locking performance. High-grade brass string posts are precision-fitted into the sealed housing to maximize wear resistance and sustain.
Engineered for flawless installation, the innovative stepped M6 flanged washer centers the string post securely via the banjo bolt without requiring tiered headstock drilling. This design eliminates tilting torque and effectively relieves mechanical stress from both the post and rear mounting screws.
