Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine represents high-precision instrument hardware engineered with an advanced 1:18 gear ratio for smooth, accurate tuning. CNC-machined components and premium brass string posts ensure tight mechanical tolerances, wear resistance, and long-term tuning stability.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post without requiring stepped headstock drilling. This design eliminates tilting torque and absorbs mechanical strain from both the post and mounting screws.
Designed with standard closed-housing dimensions matching legacy M6 specifications, it allows direct retrofitting without instrument modification. The internal mechanism comes permanently lubricated with proprietary Schaller grease for maintenance-free operation.
