Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine delivers outstanding precision and tuning comfort with its improved 1:18 gear ratio. All components are high-precision CNC-machined and surface-treated to guarantee smooth, responsive, and stable tuning performance with a self-locking drive.
Equipped with high-grade brass string posts engineered precisely into the housing, this tuning machine provides maximum tuning stability and wear-free operation. The enclosed housing comes permanently lubricated with Schaller special grease for completely maintenance-free functionality.
Featuring the innovative stepped M6 flanged washer, it eliminates tilting moment and absorbs pressure from both the post and the rear mounting screw without requiring stepped drilling in the headstock. It shares identical installation dimensions with previous models for direct drop-in replacement.
