Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine represents high-precision engineering, setting a worldwide standard for closed-type tuning machines. Built with an improved 1:18 gear ratio, it ensures precise, smooth, and effortless tuning action. Every component is CNC-machined to exact tolerances, delivering consistent performance and tuning stability across all applications.
Featuring high-grade brass string posts precisely fitted into the housing, this tuning machine provides maximum wear resistance and zero backlash. The closed housing comes permanently lubricated with specialized grease, guaranteeing a completely maintenance-free lifespan. The innovative stepped M6 flanged washer centers the string post automatically, eliminating tilting strain and eliminating the need for step-drilled headstock holes.
