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. Continuing the legacy of the original 1966 design, all components are CNC-machined to exacting tolerances and surface-finished for smooth, velvet-like tuning performance and rock-solid stability.
Featuring high-grade brass string posts engineered for maximum wear resistance, the M6 Pin incorporates an innovative stepped washer with a 0.39-inch diameter base. This design reliably centers the string post without requiring a stepped peghead hole, effectively eliminating tilting torque and reducing strain on both the shaft and rear mounting screws.
Equipped with permanently lubricated, maintenance-free closed housings and self-locking drive mechanisms, this tuning machine provides flawless long-term reliability. The two-pin design maintains a precise 0.39-inch pin spacing with a 0.31-inch distance to the post center for secure headstock attachment.
