Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio for precise and smooth tuning stability. Engineered with high-precision CNC-machined components and self-locking drive mechanisms, it delivers sensitive adjustments and dependable performance across all playing environments.
Crafted with premium brass string posts precision-fitted into the housing, these tuners eliminate play and resist wear over years of heavy use. The innovative stepped M6 flanged washer centers the string post perfectly via the hollow screw, eliminating tilting torque and removing the need for stepped headstock boreholes.
Permanently lubricated with Schaller special grease, all enclosed housings remain completely maintenance-free. Designed with identical mounting dimensions to its legacy predecessor, the M6 135 allows direct drop-in replacement without instrument modifications.
