Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets a high standard for closed guitar tuning machines with an improved 1:18 gear ratio for precise and smooth tuning comfort. All components are CNC-machined and finished with precision, featuring a self-locking drive that guarantees consistent, sensitive, and stable tuning.
Crafted with premium brass string posts precisely fitted into the housing, this tuning machine delivers high tuning stability and wear resistance. The innovative stepped M6 flanged washer centers the string post through the hollow screw, eliminating tilting torque and removing pressure from mounting screws without requiring stepped headstock holes.
Permanently lubricated with Schaller special grease, the enclosed mechanism operates completely maintenance-free. It serves as a direct replacement for previous closed models while providing modern engineering refinements and reliable performance.
