Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning stability with an advanced 1:18 gear ratio. All components are CNC-machined to exact tolerances, high-grade surface finished, and self-locking to ensure velvet-smooth, reliable operation across a range of musical applications.
Crafted with premium brass string posts precisely fitted into the housing, the M6 135 offers exceptional wear resistance and long-term durability. The innovative stepped M6 flanged washer centers the string post securely without requiring stepped peghead counterbores, effectively eliminating tilt torque and protecting mounting hardware.
Permanently lubricated with Schaller special grease, every enclosed unit is completely maintenance-free. Designed with identical mounting dimensions to its predecessor, it serves as a direct drop-in replacement without requiring guitar modifications.
