Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning precision and smooth operation with its refined 1:18 gear ratio. Designed to set the standard for closed-housing machine heads, it combines CNC-machined components with a self-locking drive for lasting pitch stability.
Equipped with high-grade brass string posts engineered for wear-free performance, each tuner integrates seamlessly into your headstock. An innovative stepped M6 flanged washer centers the string post securely without requiring stepped counterbores, effectively eliminating tilting torque and protecting mounting hardware.
Permanently lubricated with Schaller special grease, these sealed tuners remain entirely maintenance-free over years of performance. The M6 180 offers drop-in compatibility with legacy M6 housings, ensuring effortless installation and robust reliability.
