Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and tuning comfort with a refined 1:18 gear ratio. All components are CNC-machined and surface-treated, featuring a self-locking drive mechanism that guarantees smooth, sensitive, and stable tuning.
Crafted with high-grade brass string posts precisely fitted into the housing, these tuners deliver maximum tuning stability and long-lasting wear resistance. The innovative stepped M6 flanged washer centers the string post securely without requiring a stepped peghead hole, preventing tilt and reducing strain on both the post and mounting screws.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 135 matches the exact mounting dimensions of its predecessor for a direct, hassle-free replacement on compatible guitar headstocks.
