Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. As the modern evolution of the original closed-housing design introduced in 1966, it incorporates state-of-the-art engineering while preserving legendary performance.
Precision CNC-machined components and high-grade brass string posts ensure long-lasting wear resistance and tuning stability. The self-locking drive and permanently lubricated sealed housing provide completely maintenance-free, sensitive, and uniform adjustments.
Featuring the innovative stepped flanged washer, this tuning machine centers the post securely via the banjo bolt and eliminates tilting torque without requiring stepped headstock drilling. It mounts easily as a direct replacement for previous models without modifications.
