Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an improved 1:18 gear ratio. As the modern evolution of the legendary original sealed tuner introduced in 1966, this model combines classic heritage with state-of-the-art enhancements.
All components are CNC-machined to precise tolerances and surface-finished for flawless operation. The high-grade brass string posts are fitted into the housing to ensure optimal tuning stability and wear resistance, while permanent lubrication with specialized grease ensures completely maintenance-free performance.
Equipped with an innovative stepped flanged washer, this tuner allows for straightforward installation and centered post alignment without requiring a stepped peghead hole. This advanced design relieves strain on both the string post and rear mounting screw by eliminating tilting torque.
