Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 represents an advanced evolution of the legendary sealed tuning machine, offering an optimized 1:18 gear ratio for velvety-smooth, highly precise, and reliable tuning. Each component is CNC-machined to exacting tolerances and features a self-locking drive that provides unmatched tuning stability and effortless micro-adjustments.
Constructed with durable brass string posts engineered for maximum wear resistance, these tuners incorporate Schaller's innovative stepped flanged washer. This 0.39-inch diameter stepped washer self-centers the string post through the threaded bushing without requiring a stepped headstock hole, eliminating tilting torque and reducing strain on both the post and rear mounting screw.
Permanently lubricated with Schaller special grease, all internal mechanisms are completely maintenance-free. Designed for direct replacement of previous generation models, the M6 180 delivers pristine mechanical performance, rock-solid pitch retention, and exceptional longevity for premium instruments.
