Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and velvet-smooth operation with its refined 1:18 gear ratio. Continuing the legacy of the original closed-type machine head introduced in 1966, this model features high-precision CNC-machined components that provide stable, wear-free performance.
Equipped with durable brass string posts and permanently lubricated with Schaller special grease, each unit is engineered for maintenance-free reliability. The self-locking drive mechanism ensures uniform tension and consistent tuning stability under demanding playing conditions.
Installation is streamlined through the innovative stepped M6 flanged washer, which centers the string post without requiring stepped headstock drilling. This design eliminates tilting torque and protects both the post and the rear mounting screw for lasting durability.
