Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers outstanding precision and velvet-smooth tuning comfort with an upgraded 1:18 gear ratio. All components are CNC-machined to exact tolerances, surface-treated, and permanently lubricated with Schaller special grease for maintenance-free operation and exceptional durability.
Featuring premium brass string posts precisely fitted into the housing, the M6 180 provides maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer reliably centers the string post through the banjonut, eliminating tilt torque and protecting against stress on both the string post and rear fixing screw.
Designed as a direct replacement for legacy closed tuning machines, the M6 180 installs smoothly without headstock modifications. Every unit ensures rock-solid tuning stability, highly responsive micro-adjustments, and reliable self-locking performance.
