Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 represents the pinnacle of closed tuning machine engineering, building upon a legendary design with modern precision improvements. Featuring an advanced 1:18 gear ratio, it ensures exceptionally smooth, delicate, and stable tuning performance with rock-solid pitch stability.
Every component is CNC-machined to exact tolerances and finished to premium standards. The self-locking drive and precision-fitted brass posts deliver frictionless, wear-free adjustment, while the permanently lubricated internal mechanism remains completely maintenance-free over years of rigorous play.
Equipped with an innovative stepped M6 flanged washer, this tuning machine aligns the string post securely through the banjo bolt without requiring stepped headstock drilling. This smart design effectively eliminates tilting torque and protects both the mounting screw and post for maximum durability.
