Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine features a refined 1:18 gear ratio engineered for precise, velvety-smooth tuning and exceptional intonation stability. Manufactured with high-precision CNC machining and high-grade brass string posts, each enclosed tuner operates with a self-locking drive that provides uniform and sensitive adjustment.
Equipped with the innovative stepped M6 flanged washer, this system reliably centers the string post via the threaded bushing without requiring stepped headstock drilling. This optimized mechanical design directly absorbs tilt torque and minimizes lateral pressure on both the string post and rear mounting screw.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 180 easily retrofits existing instruments without modification. Each machine delivers dependable performance, durable wear resistance, and rock-solid pitch retention.
