Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets the standard for closed tuning mechanisms, combining classic heritage with refined engineering. Featuring an upgraded 1:18 gear ratio, it ensures precise, velvet-smooth tuning and exceptional tuning stability. Every component is CNC-machined and finished for exact tolerances and self-locking, maintenance-free performance.
Equipped with high-grade brass string posts precisely fitted into the housing, this tuning machine eliminates wear and provides consistent tension. The innovative stepped M6 flanged washer centers the post reliably via the hollow screw, removing tipping torque and eliminating the need for stepped headstock drilling.
Permanently lubricated with Schaller special grease, these sealed tuners provide lifetime reliability without maintenance. Engineered for easy installation with a 0.4 in (10 mm) pin spacing, they offer seamless functionality across solid headstock and locking configurations.
