Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 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 to ensure uniform, responsive, and stable tuning.
Equipped with high-grade brass string posts precisely fitted into the housing, this tuning machine provides maximum tuning stability and wear-free operation. The specialized stepped collar design enables effortless installation, eliminating tilt torque and relieving pressure from the post and mounting screw without requiring stepped headstock drilling.
Permanently lubricated with Schaller special grease for maintenance-free performance, the M6 135 features identical mounting dimensions to its predecessor for direct, drop-in replacement without instrument modification.
