Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and tuning stability. Engineered with a refined 1:18 gear ratio, it delivers ultra-smooth operation and micro-tuning accuracy for solid headstock instruments.
Every component is CNC-machined to exacting tolerances, featuring premium brass posts precisely fitted into the housing to eliminate wear. The closed housing is permanently lubricated with Schaller special grease for completely maintenance-free performance.
Equipped with an innovative stepped flanged washer, this tuning machine reliably centers the string post through the banjo bolt without requiring a stepped headstock hole, eliminating tilt and relieving pressure on the mounting pins.
