Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an upgraded 1:18 gear ratio. Continuing the legacy of the original 1966 closed-housing design, this refined edition incorporates modern enhancements while maintaining exceptional reliability.
Every component is high-precision CNC-machined and surface-finished, featuring self-locking mechanics for sensitive and stable tuning. The string posts are crafted from premium brass and seated precisely within the housing to ensure maximum tuning stability and wear resistance.
Featuring the innovative stepped M6 flanged washer, this tuner allows effortless installation and permanent shaft centering without requiring a stepped peghead bore. Permanently lubricated with specialized grease, the sealed design ensures completely maintenance-free performance.
