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 1966 closed-housing design, this modern iteration combines refined engineering with unmatched durability.
Each component is CNC-machined to exacting tolerances, featuring high-grade brass posts fitted seamlessly into the housing for maximum tuning stability and wear-free performance. The self-locking drive and specialized permanent lubrication ensure an ultra-smooth, maintenance-free tuning experience.
Equipped with an innovative stepped M6 flanged washer, this machine head centers the string post securely without requiring a stepped headstock bore. This design eliminates tilting torque and relieves mechanical stress from both the post and the rear mounting screw.
