Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers refined performance with an advanced 1:18 gear ratio for ultra-precise and smooth tuning action. Each component is CNC-machined to exacting tolerances and surface-finished, featuring high-grade brass string posts engineered for maximum tuning stability and wear resistance.
Equipped with an innovative stepped M6 flanged washer, this tuning machine reliably centers the string post through the banjo bolt without requiring a stepped peghead bore. This design eliminates tilting torque and takes mechanical strain off both the post and mounting screws.
Factory lubricated with Schaller special grease, the sealed housing provides maintenance-free operation and long-lasting durability for modern and vintage instruments alike.
