Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine combines legendary design heritage with precision engineering. Featuring a refined 1:18 gear ratio, it delivers velvety-smooth, highly accurate tuning and exceptional pitch stability. Every closed-housing unit is permanently lubricated with Schaller special grease for completely maintenance-free operation.
Precision CNC-machined components and high-grade brass string posts guarantee wear-free performance and reliable tuning retention. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt without requiring a stepped headstock counterbore, eliminating tilt torque and protecting mechanical components.
Designed with standard 0.39 in center-to-center pin spacing and an 0.31 in spacing from pin to post center, these machines provide seamless replacement and rock-solid mounting. The precision-fit assemblies ensure sensitive adjustment and consistent string tension across all playing styles.
