Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin Guitar Tuning Machine sets an industry standard for closed-type tuning machines, featuring a refined 1:18 gear ratio for smooth, precise, and effortless tuning. Each component is CNC-machined to exacting tolerances, surface-treated, and fitted with a self-locking drive mechanism to deliver uniform stability and exceptional durability.
Equipped with high-grade brass string posts that are precisely fitted into the housing, this machine head prevents wear and ensures maximum tuning stability. The stepped M6 flanged washer reliably centers the string post via the banjo bolt, effectively eliminating tilt momentum and stress on both the post and the rear mounting fixture without requiring stepped headstock drilling.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 Pin utilizes a two-pin housing design with a 10 mm (0.39 in) center-to-center pin spacing and an 8 mm (0.31 in) pin-to-post distance. This premium tuning machine offers reliable performance for modern guitarists seeking superior tuning accuracy and robust construction.
