Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets an industry benchmark for closed tuners, featuring an upgraded 1:18 gear ratio for ultra-precise and smooth tuning action. Each component is CNC-machined to exact tolerances and factory-treated with specialized lubricant for completely maintenance-free operation and exceptional durability.
Equipped with high-grade brass string posts and a self-locking drive mechanism, these tuners ensure outstanding tuning stability and wear resistance. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, removing tilt torque and eliminating the need for a stepped peghead hole.
Designed with a 0.39 in (10 mm) pin spacing and an 0.31 in (8 mm) spacing from the pin to the string post center, this model offers seamless retrofitting for compatible guitar headstocks. Each set includes banjo bolts, flanged washers, and mounting screws for complete installation.
