Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets an exceptional benchmark for enclosed guitar tuning machines, featuring an optimized 1:18 gear ratio for velvety smooth, ultra-precise tuning. Every component is CNC-machined to exact tolerances and surface-finished, while the self-locking drive delivers dependable, slip-free performance.
Crafted with premium brass string posts fitted precisely into the housing, this tuning machine provides maximum tuning stability and long-lasting wear resistance. The innovative stepped M6 flanged washer centers the post automatically through the threaded bushing without requiring a stepped headstock bore, effectively eliminating tilting torque and reducing strain on mounting hardware.
Permanently lubricated with Schaller special grease, the closed housing design remains completely maintenance-free throughout its service life. Engineered for straightforward installation and direct replacement, it delivers professional reliability and refined performance to any compatible headstock.
