Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio, delivering ultra-smooth and accurate tuning stability. Building on the iconic design established in 1966, this modern iteration incorporates CNC-machined components and high-grade brass string posts engineered directly into the housing to eliminate mechanical wear.
Featuring Schaller's innovative stepped flanged washer, this system ensures perfect centering of the string post via the hollow bolt without requiring stepped headstock drilling. This design absorbs tension and eliminates tilt torque, significantly reducing stress on both the internal gear assembly and the rear mounting screws.
Each closed-type tuner is permanently lubricated with proprietary Schaller special grease, guaranteeing entirely maintenance-free operation and long-term durability. Precision-fitted surface treatments and self-locking drive mechanics ensure reliable, sensitive performance across varied string configurations.
