Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers high-precision tuning performance with an upgraded 1:18 gear ratio for smooth, accurate string adjustments. Built upon the legacy of the original sealed tuner standard introduced in 1966, this refined model integrates modern innovations while preserving classic styling and dependable performance.
Crafted with CNC-machined components and premium brass string posts, every unit ensures precise internal fitment, maximum tuning stability, and long-term wear resistance. The internal mechanism features a self-locking drive and is permanently lubricated with Schaller special grease for completely maintenance-free operation.
Featuring the innovative stepped M6 flanged washer, installation is streamlined while providing reliable post centering through the banjo bolt. This engineering design eliminates tilting moments and reduces mechanical stress on both the string post and rear mounting screw.
