Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 series sets a high standard for closed tuning machines, combining timeless design with modern engineering. Engineered with a 1:18 gear ratio, it delivers ultra-precise, velvet-smooth tuning and exceptional pitch stability. Every component is CNC-machined to exacting tolerances and surface-finished for flawless, long-lasting performance.
Equipped with high-grade brass string posts fitted directly into the housing, these tuners eliminate play and maximize wear resistance. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, preventing tilt momentum and relieving mechanical stress without requiring stepped headstock peg holes.
Permanently lubricated with Schaller special grease, the M6 180 tuning machines are completely maintenance-free and provide consistent, delicate tuning response. They are engineered to replace standard legacy housings effortlessly while maintaining rock-solid string tension and tuning reliability.
