Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 Guitar Tuning Machine delivers exceptional tuning accuracy and velvety-smooth operation through a refined 1:18 gear ratio. CNC-machined to precise tolerances and finished to the highest standards, all components ensure velvety, sensitive, and completely stable tuning response with self-locking functionality.
Crafted from premium brass, the posts fit precisely into the sealed housing to guarantee maximum tuning stability and wear-free performance. Each enclosed tuning machine is lubricated for life with specialized Schaller grease, making the entire mechanism completely maintenance-free.
Featuring the innovative stepped M6 flanged collar, this design effortlessly centers the string post via the hollow bolt without requiring stepped drilling in the headstock. This configuration eliminates tilting moment and relieves mechanical stress from both the string post and rear mounting screw.
