Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets a benchmark for closed-type tuners, engineered with a 1:18 gear ratio for exceptionally smooth and precise tuning accuracy. All components are CNC-machined to exacting tolerances and treated with specialized surface finishes to deliver reliable, sensitive, and stable performance.
Featuring high-grade brass string posts meticulously fitted into the housing, this tuner maximizes tuning stability and eliminates wear during regular operation. The integrated stepped flanged washer centers the string post securely through the banjo bolt, removing tilting torque and stress from the mounting components without requiring stepped drilling in the headstock.
Permanently lubricated with Schaller proprietary grease, the closed housing design ensures complete maintenance-free operation over its lifespan. The standardized two-pin layout provides solid alignment on compatible electric and acoustic guitar headstocks.
