Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation, built upon the legendary closed-housing design first introduced in 1966. Featuring an enhanced 1:18 gear ratio, this premium machine head ensures ultra-precise adjustments and long-lasting pitch stability for electric and acoustic guitars.
Engineered with precision CNC machining, each component utilizes high-grade brass posts fitted seamlessly into the housing to eliminate wear. The closed casing is permanently lubricated with specialized grease for completely maintenance-free performance and consistent gear engagement.
Installation is optimized through the innovative stepped collar washer, which reliably centers the string post without requiring a stepped headstock bore. This advanced design relieves mechanical strain on both the string axis and rear mounting screws to ensure superior structural longevity.
