Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Engineered with high-precision CNC-machined components and surface finishes, it features a self-locking drive that ensures consistent, sensitive, and stable tuning performance.
Crafted with premium brass string posts precision-fitted into the housing, this tuning machine provides maximum tuning stability and wear-free operation. The enclosed housing comes permanently lubricated with Schaller special grease, making the entire mechanism completely maintenance-free.
Featuring the innovative stepped M6 flanged washer with a 0.39 in (10 mm) diameter base, the string post centers reliably via the banjo bolt without requiring stepped drilling in the headstock. This design eliminates tilting torque and relieves mechanical stress on both the post and the rear mounting screw.
