Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 represents a modern evolution of the iconic closed-gear tuner, delivering exceptional tuning accuracy with its refined 1:18 gear ratio. Every component is CNC-machined to exacting tolerances and treated with high-grade surface finishing, ensuring velvet-smooth operation and enduring mechanical stability.
Equipped with premium brass string posts carefully fitted into the housing, this tuning machine provides maximum wear resistance and pitch reliability. The specialized stepped M6 flanged washer centers the post securely through the headstock hole, eliminating tilting torque and removing unwanted strain from both the string post and mounting screw.
Engineered for effortless drop-in installation, the M6 135 shares identical mounting dimensions with its classic predecessor, allowing modification-free retrofits. Each enclosed housing is permanently lubricated with Schaller special grease for maintenance-free longevity.
