Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio, delivering velvet-smooth and exceptionally accurate tuning control. Built upon the legendary closed-housing design established in 1966, this upgraded model features CNC-machined components with premium surface finishes and a self-locking drive mechanism for uncompromising pitch stability.
Crafted with premium brass string posts precisely fitted into the housing, these tuners ensure zero wear and maximum reliability during intense playing. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring stepped headstock drilling, effectively eliminating tilting torque and reducing mechanical stress.
Permanently lubricated with specialized Schaller grease, these closed machine heads provide maintenance-free performance over their entire lifespan. Designed for seamless replacement on standard headstocks, they combine classic aesthetics with modern durability and effortless operation.
