Schaller M6 135 Tuning Machine

The Schaller M6 135 tuning machine sets the standard for closed guitar tuners, featuring an upgraded 1:18 gear ratio that delivers precise tuning and exceptional smoothness. Each component is CNC-machined with high accuracy and surface finished to ensure sensitive, uniform, and stable performance.
Equipped with high-grade brass string posts engineered precisely into the housing, this tuning machine provides maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped peghead bore, eliminating tilting torque and reducing pressure on the mounting screws.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 135 retains the exact installation dimensions of its predecessor for an effortless direct replacement.
