Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 represents a legendary benchmark in enclosed guitar tuning machines, engineered with a refined 1:18 gear ratio for ultra-precise and smooth tuning comfort. All internal components are CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for completely maintenance-free operation.
Crafted with premium high-grade brass posts fitted seamlessly into the housing, this tuning machine ensures maximum tuning stability and wear resistance. The self-locking drive mechanism provides a uniform, delicate, and solid tuning experience across all playing conditions.
Featuring the innovative stepped M6 flanged washer, it centers the string post securely through the threaded bushing without requiring a stepped headstock bore. This design eliminates tilting torque and relieves mechanical stress from both the post and the rear mounting screw.
