Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 tuning machine delivers superior precision and tuning stability, featuring an upgraded 1:18 gear ratio for smooth and fine adjustment. Built upon the legendary closed-housing design established in 1966, this modern version incorporates refined engineering and premium materials.
Precision CNC-machined components and solid brass posts ensure wear-free performance, high durability, and self-locking drive consistency. All closed tuners are permanently lubricated with specialized Schaller grease, providing maintenance-free operation across their lifetime.
Equipped with an innovative stepped M6 flanged washer, this system centers the string post securely without requiring stepped headstock drilling. This design absorbs mechanical pressure and eliminates tilting moments, safeguarding your instrument's headstock and mounting hardware.
