Schaller M6 Mini Guitar Tuning Machine

The Schaller M6 Mini guitar tuning machine delivers legendary performance in a smaller, lighter format optimized for guitars with compact headstocks, Stratocaster-style models, and 12-string instruments. Engineered with a precise 1:18 gear ratio, it provides smooth, velvety tuning and exceptional tuning stability. Each tuner is permanently lubricated with Schaller special grease for completely maintenance-free operation.
Precision-engineered brass string posts and high-tolerance internal components ensure reliable tuning accuracy, low friction, and long service life. The self-locking drive maintains consistent tension and eliminates slip during aggressive playing and string bends.
Equipped with Schaller's innovative stepped collar washer (0.39 in / 10 mm diameter), the M6 Mini centers the post via the banjo bolt and eliminates tilting torque without requiring stepped headstock drilling. This relieves mechanical pressure on both the post and mounting screw for optimal reliability.
