Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and velvet-smooth tuning performance with its refined 1:18 gear ratio. All components are CNC-machined to exact tolerances, high-grade surface finished, and permanently lubricated with Schaller special grease for maintenance-free operation and exceptional durability.
Equipped with high-grade brass string posts engineered precisely into the housing, this machine head offers maximum tuning stability and wear-free functionality. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, preventing tilt and reducing strain on both the post and rear mounting screw without requiring stepped peghead drilling.
Engineered for flawless reliability and seamless retrofitting, the self-locking drive ensures smooth, sensitive, and rock-solid string tension adjustments across all playing styles.
