Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. Engineered as a closed-gear tuner, it upholds the legendary M6 legacy with refined components designed for modern performance and maximum tuning stability.
Every component is CNC-machined to precise tolerances and surface-finished for smooth operation, featuring high-grade brass posts engineered for wear-free longevity. The self-locking drive ensures consistent and delicate tuning response, while permanent internal lubrication with Schaller special grease provides completely maintenance-free functionality.
Installation is streamlined via the innovative stepped M6 flanged washer, which centers the string post securely through the banjo bolt without requiring stepped headstock drilling. This design eliminates tilting torque, reducing physical stress on both the post and rear mounting screws to preserve your instrument's structural integrity.
