Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning stability, featuring a refined 1:18 gear ratio for smooth, velvety adjustment. CNC-machined components and surface finishes ensure self-locking, consistent operation without slipping.
Built with premium brass string posts carefully fitted into closed housings, this tuner guarantees maximum durability and zero-wear longevity. An innovative stepped M6 flanged washer reliably centers the string post without requiring stepped headstock drilling, effectively eliminating tilt and lateral pressure.
Permanently lubricated with Schaller special grease, the sealed housing provides completely maintenance-free operation. Engineered to fit standard configurations seamlessly, it serves as an effortless drop-in upgrade for modern and vintage instruments alike.
