Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a high standard for closed tuning mechanisms, combining legendary heritage with modern precision engineering. Equipped with an upgraded 1:18 gear ratio, it delivers ultra-precise, velvety smooth tuning comfort and exceptional pitch stability for demanding players.
Every component is CNC-machined to exacting tolerances, surface-finished, and permanently lubricated with Schaller special grease for completely maintenance-free operation. The high-grade brass string posts fit precisely into the housing to eliminate play, minimize wear, and ensure reliable long-term performance.
Installation is streamlined thanks to the stepped M6 flanged washer, which centers the string post without requiring stepped headstock boreholes and eliminates tilting torque. Designed with a dual-pin configuration, it provides secure mounting and direct compatibility with standard 10 mm pin spacings.
