Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets a high standard for closed tuning machines, featuring an advanced 1:18 gear ratio for velvety smooth and exceptionally precise guitar tuning. Each component is CNC-machined to exacting tolerances and treated with a premium surface finish, while self-locking drive mechanics ensure stable and dependable performance.
Crafted from high-grade brass, the string posts fit seamlessly into the housing to maximize tuning stability and eliminate mechanical wear. The innovative stepped M6 flanged collar reliably centers the string post through the threaded bushing, eliminating tilting torque and protecting the instrument headstock from excessive pressure.
Permanently lubricated with specialized Schaller grease, these sealed tuners operate completely maintenance-free. Designed for versatile compatibility, the M6 180 replaces predecessor models effortlessly without requiring structural modifications to your guitar headstock.
