Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed tuners, featuring an upgraded 1:18 gear ratio that delivers exceptional precision and smooth tuning control. Every component is CNC-machined to precise tolerances and surface-finished to ensure lasting, friction-free performance across diverse playing styles.
Equipped with high-grade brass posts precisely fitted to the housing, this machine head provides maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt without requiring a stepped headstock bore, effectively eliminating tilting torque and reducing mechanical strain.
Engineered for completely maintenance-free operation, each sealed housing is permanently lubricated with Schaller special grease. Designed with dual locating pins spaced at 0.39 in (10 mm) center-to-center, the M6 Pin offers a seamless replacement option for legacy single-pin Schaller configurations.
