Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 Guitar Tuning Machine sets an industry standard for sealed tuners, featuring an upgraded 1:18 gear ratio that delivers exceptional tuning precision and ultra-smooth operation. Every component is CNC-machined to exacting tolerances and surface-finished, ensuring consistent, wear-free performance and high tuning stability powered by a self-locking drive mechanism.
Crafted with premium brass string posts precisely fitted into the housing, these tuners eliminate play and maximize durability. The innovative stepped M6 flanged washer centers the string post securely via the hollow screw, preventing tilt and reducing pressure on the mounting screws without requiring stepped drilling in the headstock.
Permanently lubricated with Schaller special grease for entirely maintenance-free longevity, the M6 180 is engineered for direct drop-in replacement on existing standard headstocks. Each set comes complete with threaded bushings, stepped washers, and mounting screws for straightforward installation.
