Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. All components are CNC-machined to precise tolerances and surface-finished for consistent, friction-free performance and long-term durability.
Equipped with high-grade brass string posts meticulously fitted into the housing, these tuners provide superior tuning stability and wear resistance. The innovative stepped M6 flanged washer centers the post securely through the threaded bushing without requiring stepped headstock drilling, effectively eliminating tilt torque.
Featuring permanently lubricated, fully sealed internal gears treated with specialized grease, the M6 180 ensures completely maintenance-free performance. It replaces legacy M6 housings directly without headstock modification, offering professional-grade reliability across solid and slotted configurations.
