Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning comfort with an upgraded 1:18 gear ratio. Continuing the legacy of the original closed-housing design established in 1966, this modern iteration incorporates advanced engineering enhancements for optimal performance.
Every component is precision CNC-machined and surface-finished, featuring self-locking mechanics that ensure smooth, sensitive, and stable tuning. The string posts are crafted from high-grade brass and fitted precisely into the housing to maximize tuning stability and provide long-lasting wear resistance.
Equipped with an innovative stepped M6 flanged washer, this tuner allows straightforward mounting without the need for a stepped peghead hole. Permanently lubricated with Schaller special grease, the sealed housing provides maintenance-free operation and protects internal mechanisms from wear.
