Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers premium tuning comfort and high accuracy, featuring an advanced 1:18 gear ratio for smooth, precise adjustment. Engineered with precision CNC-machined components and a self-locking drive, this closed tuner provides exceptional stability and sensitive control.
Crafted with premium brass string posts fitted precisely into the housing, the M6 180 guarantees maximum tuning stability and wear-free operation. All enclosed mechanisms are permanently lubricated with Schaller special grease to remain completely maintenance-free throughout their lifespan.
The innovative stepped M6 flanged washer ensures straightforward installation and reliable post centering via the hollow screw, eliminating the need for a stepped headstock bore. This functional design eliminates tilting torque and reduces mechanical stress on both the post and rear mounting screws.
