Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine features a 1:18 gear ratio that provides precise and smooth tuning performance. Precision CNC-machined components and a self-locking drive mechanism ensure consistent operation and long-term tuning stability.
Equipped with high-grade brass string posts and permanently lubricated with Schaller special grease, this closed tuner design operates completely maintenance-free. The innovative stepped M6 flanged washer centers the string post reliably without requiring stepped drilling in the headstock.
This design eliminates tilting torque and reduces mechanical strain on both the post and the rear mounting screw for optimal durability. It is engineered for straightforward replacement and reliable performance across various solid and slotted headstock configurations.
