The Schaller M6 180 guitar tuning machine delivers outstanding precision and exceptional tuning comfort with an upgraded 1:18 gear ratio. All components are CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for completely maintenance-free operation and ultra-smooth performance.
Crafted with premium brass string posts precision-fitted into the housing, this closed machine head ensures maximum tuning stability and wear-free longevity. The self-locking drive mechanism provides sensitive, even, and reliable response across all tuning adjustments.
Featuring the innovative stepped M6 flanged washer, the unit mounts securely while properly centering the string post to eliminate tilt and relieve mechanical strain without requiring stepped headstock holes.
