Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers legendary performance with an upgraded 1:18 gear ratio for velvety smooth and exceptionally precise tuning. Each component is CNC-machined to exact tolerances, surface-finished, and permanently lubricated with Schaller special grease for completely maintenance-free operation.
Featuring high-grade brass string posts engineered directly into the housing, this machine head guarantees maximum tuning stability and wear-free longevity. The self-locking drive mechanism provides consistent, sensitive response to keep your instrument perfectly in tune through demanding performances.
Equipped with the innovative stepped M6 flanged washer, it centers the string post reliably over the banjo bolt without requiring stepped headstock drilling. This design eliminates tilting torque and relieves mechanical stress from both the post and the rear mounting screw for direct, modification-free retrofitting.
