Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine offers precise functionality and smooth operation with an improved 1:18 gear ratio. All components are CNC-machined and surface-treated, featuring a self-locking drive that provides consistent, sensitive, and stable tuning performance.
Crafted with high-grade brass string posts precisely fitted into the housing, these tuners ensure lasting tuning stability and wear resistance. The innovative stepped M6 flanged washer centers the string post securely over the hollow screw, eliminating tipping torque and reducing strain on the mounting screw without requiring a stepped peghead bore.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 135 features identical installation dimensions to its predecessor for direct replacement without instrument modifications.
