Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth tuning stability. Featuring an improved 1:18 gear ratio, each tuner provides precise, velvety-smooth operation. All components are CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for completely maintenance-free performance.
Equipped with high-grade brass string posts precisely fitted into the housing, these tuners deliver maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer ensures solid shaft centering and simple installation without requiring stepped headstock boreholes, effectively eliminating tilting torque and reducing stress on mounting components.
Designed with identical installation dimensions to its predecessor, the M6 135 allows direct replacement and upgrades on existing instruments without modifications. Included mounting hardware ensures seamless integration for premium instrument builds and repairs.
