Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with its refined 1:18 gear ratio. Continuing the legacy of the original closed-type design, this model integrates modern innovations to provide superior stability and long-lasting performance for precision instrument tuning.
Crafted with CNC-machined components and high-grade brass posts, every unit ensures wear-free reliability and self-locking stability. The permanently lubricated enclosed housing uses specialized Schaller grease to ensure completely maintenance-free operation over extended playing periods.
Equipped with an innovative stepped M6 flanged washer, this tuning machine centers the string post securely through the banjo bolt without requiring stepped headstock drilling. This advanced design eliminates tilting moment and reduces mechanical stress on mounting screws and posts.
