Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers precision and tuning comfort with its refined 1:18 gear ratio. As the modern evolution of the classic closed tuning machine design first established in 1966, it incorporates state-of-the-art manufacturing while retaining legendary performance.
Every component is CNC-machined to exacting tolerances and surface-treated for lasting durability. The high-grade brass string posts fit precisely into the housing to ensure optimal tuning stability, wear-free operation, and a velvet-smooth action supported by permanent lubrication.
Equipped with an innovative stepped M6 flanged washer, this tuning machine simplifies installation and provides solid post centering without requiring a stepped headstock bore. It retrofits seamlessly into existing setups while eliminating tilting moment and reducing mounting pressure.
