Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets an industry benchmark with its advanced 1:18 gear ratio, delivering ultra-precise, velvet-smooth tuning and maximum tuning stability. CNC-machined to exacting tolerances, every component features a self-locking drive and premium brass string posts engineered for wear-free, long-lasting performance.
An innovative stepped M6 flanged washer ensures effortless assembly and permanent shaft centering over the banjonut, eliminating the need for a stepped headstock bore. This specialized design effectively prevents tilting moments and relieves mechanical stress from both the post and the rear mounting screw.
Permanently lubricated with Schaller special grease, these sealed tuners operate completely maintenance-free. Designed as a direct drop-in replacement for earlier models, the M6 180 combines modern precision engineering with legendary reliability.
