Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets a high standard for closed tuning systems, featuring an upgraded 1:18 gear ratio for velvety smooth, precise tuning control. All structural components are CNC-machined to exacting tolerances and surface-finished, while high-grade brass posts ensure optimal tuning stability and wear resistance.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine reliably centers the string post without requiring a stepped headstock hole. This design eliminates tilting torque and distributes pressure evenly across the mounting assembly, protecting instrument headstocks and preserving component longevity.
Permanently lubricated with specialized Schaller grease for completely maintenance-free operation, the M6 Pin incorporates a self-locking drive mechanism. Designed with dual mounting pins positioned 0.4 in apart center-to-center, it provides secure, stable installation on electric and acoustic guitars.
