Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. Continuing the legacy of the original 1966 design, this closed tuner features high-precision CNC-machined components with a self-locking drive mechanism for exceptionally smooth, sensitive, and stable performance.
Crafted with premium brass string posts fitted precisely into the housing, these tuners ensure maximum tuning stability and long-lasting wear resistance. Each unit is permanently lubricated with specialized Schaller grease, making the internal enclosed mechanism completely maintenance-free.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post without requiring a stepped peghead bore. This design eliminates tilting torque and relieves mechanical stress from both the post and the rear mounting screw for optimal instrument protection.
