Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers outstanding precision and tuning stability with an upgraded 1:18 gear ratio. Designed for smooth, velvet-like operation, each component is CNC-machined and finished to exacting tolerances, while high-grade brass string posts provide durable, wear-free performance.
Featuring the innovative stepped M6 flanged bushing, this tuning machine centers the string post automatically via the threaded bushing, eliminating the need for a stepped headstock bore. This design eliminates tilting torque and protects both the post and the rear mounting screw from excessive mechanical strain.
Permanently lubricated with Schaller special grease for maintenance-free operation, the closed housing fits seamlessly into standard installations. It serves as a direct, drop-in replacement for earlier models while providing modern performance and exceptional reliability.
