Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine sets a benchmark for closed guitar tuning systems, featuring a refined 1:18 gear ratio that provides precise, velvety-smooth tuning action and exceptional pitch stability. Every component is CNC-machined to exacting tolerances and treated with a durable surface finish, driven by a self-locking mechanism that guarantees reliable performance.
Equipped with high-grade brass string posts engineered seamlessly into the housing, this tuning machine eliminates wear and supports lasting structural integrity. The innovative stepped M6 flanged washer centers the string post securely via the hollow screw, removing lateral tilt and making stepped headstock boreholes obsolete.
Each closed mechanism is permanently lubricated with Schaller special grease for completely maintenance-free operation. Designed with a dual-pin mounting configuration spaced at 0.39 in (10 mm) center-to-center, it offers smooth installation and steadfast alignment across standard solid headstocks.
