Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark for enclosed tuners with its refined 1:18 gear ratio, delivering velvet-smooth action, precise tuning stability, and exceptional accuracy. All components are CNC-machined to exact tolerances and surface-finished, featuring a self-locking drive mechanism that ensures stable and sensitive string adjustment.
Engineered for enduring performance, each brass string post is fitted into the housing to minimize wear and maintain dependable pitch over time. The innovative stepped M6 flanged washer centers the post reliably through the banjo bolt, eliminating tilting moment and removing stress from both the post and mounting screw without requiring stepped headstock drilling.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 135 features identical installation dimensions to its predecessor for direct, seamless replacement. It accommodates a wide variety of configurations to suit standard and slotted headstocks alike.
