Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision and performance in closed tuning mechanisms. Featuring an enhanced 1:18 gear ratio, it provides exceptionally smooth and accurate tuning stability for standard and high-performance instruments.
Every component is CNC-machined to exacting tolerances, featuring high-grade brass string posts engineered for maximum durability and wear resistance. The self-locking internal drive mechanism is permanently lubricated with Schaller special grease, ensuring maintenance-free operation.
Equipped with an innovative stepped M6 flanged collar with a 0.39 in diameter, this tuner reliably centers the post without requiring stepped headstock boreholes. This design eliminates tilting torque and reduces direct mechanical stress on the post and rear mounting screws.
