Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine features a refined 1:18 gear ratio engineered for velvet-smooth operation and precise tuning accuracy. Setting the global benchmark for enclosed tuners since 1966, this updated edition incorporates CNC-machined components, premium brass string posts, and permanent lubrication with Schaller special grease for entirely maintenance-free performance.
Equipped with an innovative stepped M6 flanged washer, this tuning machine provides self-centering alignment through the headstock without requiring counterbore drilling. This dedicated mechanism eliminates tilting torque while dispersing string tension away from both the post and the rear mounting screw to maximize overall tuning stability.
Featuring slightly refined housing dimensions compared to its vintage predecessor, the M6 180 directly retrofits standard mounting patterns without instrument modifications. Its self-locking drive and precision-fitted internal brass gearing ensure consistent, wear-free adjustment across demanding playing environments.
