Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Designed as an evolution of the legendary original sealed tuner, it features high-precision CNC-machined components and surface finishes that provide consistent and stable tuning.
Equipped with high-grade brass string posts precisely fitted into the housing, this tuning machine ensures maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer reliably centers the string post through the banjo bolt, eliminating tipping moments and the need for a stepped headstock bore.
Permanently lubricated with Schaller special grease, all enclosed tuners are completely maintenance-free. The compact housing design allows for seamless replacement without modification, delivering modern engineering and reliability to your instrument.
