Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional precision and tuning comfort with an upgraded 1:18 gear ratio. Continuing the legacy of the original 1966 sealed tuner, this design integrates modern technical innovations to ensure smooth and reliable operation.
Precision CNC-machined components and high-grade brass string posts provide wear-free longevity and unmatched tuning stability. A self-locking drive and lifetime lubrication with specialized grease ensure seamless, maintenance-free performance.
The innovative stepped flange washer reliably centers the string post without requiring stepped headstock drilling. This construction effectively eliminates tilting torque and reduces mechanical strain on both the post and rear mounting screw.
