Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers outstanding tuning stability and smooth, precise action powered by an improved 1:18 gear ratio. All components are CNC-machined to exact tolerances, surface-treated, and permanently lubricated with Schaller special grease for entirely maintenance-free operation.
Featuring high-grade brass string posts engineered for maximum wear resistance, this tuner incorporates the innovative stepped M6 flanged washer. Designed with a 0.39-inch diameter step, it centers the string post securely through the banjo bolt without requiring step-drilling into the headstock, effectively eliminating tilting torque and reducing strain on mounting points.
Engineered with a standard 0.39-inch pin-to-pin spacing and a 0.31-inch distance from the pins to the post center, the M6 Pin offers direct compatibility with existing M6 footprints while providing self-locking drive mechanics for reliable performance.
