The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an optimized 1:18 gear ratio. All components are CNC-machined to exact tolerances, premium surface-finished, and driven by a self-locking mechanism for maximum stability and tuning accuracy.
Crafted with premium brass posts precisely fitted into closed housings, each unit is permanently lubricated with specialized Schaller grease for maintenance-free operation. The innovative stepped M6 flanged washer ensures effortless installation and solid post centering without requiring a stepped peghead hole.
