Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an optimized 1:18 gear ratio. Each component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for smooth, maintenance-free performance.
Equipped with high-grade brass string posts and a self-locking drive mechanism, this tuning machine provides maximum tuning stability and wear resistance. The innovative stepped M6 flanged collar reliably centers the string post without requiring stepped headstock holes, eliminating tilt and relieving pressure on the mounting screws.
Featuring a dual-pin configuration with a 0.39 in center-to-center pin spacing and an 0.31 in distance from pins to string post center, this machine head offers straightforward mounting and solid axis alignment for modern headstock designs.
