Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin tuning machine delivers legendary precision and superior tuning comfort with an upgraded 1:18 gear ratio. Designed with CNC-machined components and high-grade brass string posts fitted directly into the closed housing, it provides smooth, velvety turning and exceptional tuning stability.
Featuring the innovative stepped M6 flanged washer with a 0.39-inch diameter step, this tuning machine reliably centers the string post via the hollow bolt without requiring a stepped headstock hole. This mechanism eliminates tilt moment and relieves operational stress from both the post and rear mounting screws.
Each closed-housing unit is permanently lubricated with Schaller special grease for completely maintenance-free operation. Built with a precise 0.39-inch pin spacing, it offers seamless replacement for earlier single-pin M6 models while delivering modern wear-resistant performance.
