Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning precision and stability with its refined 1:18 gear ratio. All components are CNC-machined to exacting tolerances and surface-finished, featuring a self-locking drive mechanism that ensures smooth, responsive, and reliable tuning performance across all applications.
Equipped with high-grade brass string posts precision-fitted into the housing, the M6 180 provides maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer centers the string post accurately via the threaded bushing, eliminating tilting torque and removing stress from both the post and rear mounting screw without requiring stepped headstock holes.
Permanently lubricated with Schaller special grease, each sealed tuner offers maintenance-free operation. The streamlined housing seamlessly replaces previous generation M6 units without headstock modification, providing an effortless upgrade for premium electric and acoustic guitars.
