Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers state-of-the-art precision and exceptional tuning stability. Featuring an upgraded 1:18 gear ratio, it ensures velvet-smooth, fine-tuned adjustments for demanding musicians and instruments.
All components are CNC-machined to exact tolerances, premium finished, and engineered with a self-locking drive mechanism. High-grade brass string posts fit precisely into the housing, while lifetime lubrication with Schaller special grease ensures completely maintenance-free operation.
An innovative stepped M6 flanged washer centers the string post securely through the banjo bolt without requiring a stepped headstock bore. This functional design absorbs string tension, eliminates tilting torque, and simplifies mounting on solid and slotted headstocks alike.
