Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an upgraded 1:18 gear ratio. Each component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for smooth, maintenance-free operation and exceptional stability.
Equipped with high-grade brass posts engineered for wear-free performance, this sealed tuning machine incorporates an innovative stepped flanged washer. The stepped design automatically centers the string post within a 0.39 in headstock hole, eliminating tilting torque and reducing strain on mounting components without requiring stepped counterbores.
Featuring a dual-pin mounting design with a 0.39 in pin spacing and a 0.31 in center-to-post distance, the M6 Pin offers direct fitment and dependable mechanical alignment for modern headstocks.
