Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine features a refined 1:18 gear ratio, delivering smooth, precise tuning control and exceptional pitch stability. Engineered with high-precision CNC-machined components and self-locking drive mechanisms, this enclosed tuner ensures sensitive adjustment without slippage or backlash.
Crafted with premium brass string posts fitted precisely into the housing, the M6 135 is permanently lubricated with Schaller special grease for maintenance-free operation. The innovative stepped flanged washer centers the string post securely through the threaded bushing without requiring a stepped headstock bore, effectively eliminating tilting torque and reducing strain on the rear mounting screw.
Designed with identical installation dimensions to its classic predecessor, the M6 135 allows direct replacement and upgrades without headstock modifications. It provides reliable tuning performance across diverse configurations and demands.
