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 exact tolerances and surface-treated for ultra-smooth, self-locking operation.
Equipped with high-grade brass string posts engineered for maximum durability and wear resistance, each sealed tuner is permanently lubricated with specialized Schaller grease for maintenance-free performance.
The innovative stepped M6 flanged washer ensures straightforward installation and precise string post centering without requiring a stepped headstock hole, eliminating tilting forces and pressure on mounting screws.
