Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers state-of-the-art performance with an advanced 1:18 gear ratio, providing unprecedented precision and smooth tuning comfort. Maintaining the identical installation dimensions of its legendary predecessor, it allows for effortless replacement and upgrades without requiring instrument modifications.
Precision CNC-machined components with premium surface finishes ensure velvet-smooth, stable adjustment through a self-locking drive mechanism. Premium brass string posts are fitted precisely into the housing to guarantee maximum tuning stability and wear-free operation over extended use.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post via the threaded bushing without needing a stepped hole in the headstock. Sealed and permanently lubricated with Schaller special grease, the mechanism is completely maintenance-free and engineered for lasting reliability.
