Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 represents an advanced evolution of the legendary enclosed tuning machine standard. Featuring a refined 1:18 gear ratio, it provides smooth, precise, and highly responsive tuning comfort with exceptional tuning stability. All structural components are precision CNC-machined and finished to ensure flawless operation and long-term wear resistance.
Equipped with high-grade brass string posts engineered seamlessly into the housing, the M6 180 maximizes mechanical precision. The stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring a stepped headstock bore, effectively eliminating tilting torque and reducing strain on mounting screws.
Permanently lubricated with specialized Schaller grease, these sealed tuning machines offer completely maintenance-free performance. Designed to fit standard headstock configurations, they can directly replace legacy M6 models without headstock modification.
