Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 Guitar Tuning Machine sets an industry standard with an upgraded 1:18 gear ratio that delivers precise and smooth tuning performance. Precision CNC-machined components and high-grade brass posts ensure optimal tuning stability, wear resistance, and sensitive adjustments.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post through the banjo bolt without requiring a stepped headstock bore. This design eliminates tilting torque and reduces mechanical strain on both the post and rear mounting screw.
Permanently lubricated with Schaller special grease, the sealed housing provides completely maintenance-free operation. Engineered as a direct replacement for legacy closed tuners, it offers advanced functionality across diverse instrument setups.
