Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with its refined 1:18 gear ratio. Engineered with CNC-machined precision components and a self-locking drive, it provides uniform, sensitive adjustment and dependable tuning stability for demanding players.
Crafted with premium brass posts fitted directly into the closed housing, each tuner is permanently lubricated with Schaller special grease for completely maintenance-free performance. The innovative stepped M6 flanged washer centers the string post securely without requiring stepped headstock drilling, eliminating tilt torque and protecting mounting screws.
Featuring slightly refined housing dimensions, the M6 180 serves as a direct, modification-free replacement for previous M6 iterations. It is engineered to deliver enduring durability, pristine mechanical response, and superior pitch retention across various headstock configurations.
