Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning comfort with an optimized 1:18 gear ratio. Engineered as the modern evolution of the legendary original closed tuner, it combines CNC-machined components with a self-locking drive for smooth, consistent, and exceptionally stable tuning.
Crafted with premium brass string posts precisely fitted into the housing, each unit ensures maximum wear resistance and tuning stability. The closed housing comes permanently lubricated with Schaller special grease, providing completely maintenance-free operation across years of performance.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post via the hollow screw. This smart design eliminates tilting torque and relieves mechanical stress from both the post and mounting screw without requiring a stepped headstock bore.
