Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an advanced 1:18 gear ratio. CNC-machined components and high-grade brass posts ensure maximum tuning stability and wear-free performance for demanding musicians.
Featuring the innovative stepped M6 flanged washer, this tuner allows effortless installation and precise centering of the string post via the hollow bolt. This design eliminates tilting torque and relieves mechanical stress from both the post and the rear mounting screw.
Permanently lubricated with Schaller special grease, the sealed housing provides completely maintenance-free longevity. Designed to fit without headstock modification, it serves as a reliable direct replacement or upgrade for modern guitars.
