Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an advanced 1:18 gear ratio. Continuing the legacy of the original 1966 design, this closed-type machine head features high-precision CNC-machined components with refined surface finishes and a self-locking drive for uniform, delicate, and stable tuning.
Crafted with premium brass string posts that fit precisely into the housing, the M6 180 provides maximum tuning stability and wear-free performance. The stepped M6 flanged washer reliably centers the string post via the banjonut, eliminating tilting torque and removing pressure from both the post and mounting screw without requiring a stepped headstock hole.
Permanently lubricated with specialized grease, these sealed tuners are completely maintenance-free. Designed for easy retrofit without modifications, the M6 180 offers an effortless upgrade for superior instrument reliability and performance.
