Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents an evolution of the closed-gear industry benchmark, combining iconic design with refined mechanical performance. Engineered with a precise 1:18 gear ratio, it ensures exceptionally smooth, fine-tuned pitch adjustment and outstanding tuning stability for demanding players.
Every component is precision CNC-machined and finished with durable surface coatings. Featuring self-locking drives, permanently lubricated internal gears with Schaller specialty grease, and premium brass string posts, these sealed machine heads operate completely maintenance-free while eliminating wear over extensive play.
An innovative stepped M6 flanged washer with a 0.39 in (10 mm) diameter base simplifies installation by automatically centering the string post via the threaded bushing. This specialized design eliminates tilting moments and absorbs tension directly, protecting both the post and the rear mounting screws without requiring stepped headstock boreholes.
