Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation, built upon the legendary closed-housing design that established a global standard in 1966. Refined with advanced engineering, it incorporates an upgraded 1:18 gear ratio that enables precise and velvety tuning adjustments for demanding musicians.
Every component is CNC-machined to exact tolerances and expertly finished, featuring durable solid brass string posts precisely seated within the housing to ensure optimal tuning stability and wear resistance. The self-locking internal drive mechanism provides consistent, sensitive response, while permanent lubrication with specialized Schaller grease guarantees maintenance-free longevity.
Featuring the innovative stepped M6 flanged washer with a 0.39 in (10 mm) base diameter, this design securely centers the string post through the banjonut without requiring stepped peghead drilling. This clever construction eliminates tilting moments and relieves mechanical stress from both the post and rear mounting screws for a reliable installation.
