Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio, delivering ultra-smooth and accurate tuning stability. Building on the legendary design of the original closed-housing tuner, it incorporates modern refinements to provide outstanding tuning comfort and reliability.
Crafted with high-precision CNC machining and premium brass string posts, every component is engineered for wear-free durability and maximum stability. The self-locking gear drive ensures consistent, sensitive adjustments, while Schaller special grease provides permanent, maintenance-free lubrication.
Featuring the innovative stepped flanged washer with a 0.39-inch (10 mm) base, the tuner centers the string post perfectly through the banjo bolt without requiring counterbores in the headstock. This smart design eliminates tilting moments and relieves mechanical stress on both the post and mounting screws.
