Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and tuning comfort with an upgraded 1:18 gear ratio. Designed with CNC-machined components and a self-locking drive mechanism, it ensures sensitive, smooth, and exceptionally stable tuning performance.
Featuring high-grade brass posts precision-fitted into the housing, this tuning machine delivers high tuning stability and wear resistance. The innovative stepped M6 flanged washer centers the string post securely without requiring a stepped headstock bore, eliminating tilting torque and reducing pressure on mounting screws.
All enclosed machine heads are permanently lubricated with Schaller special grease for completely maintenance-free operation. Built with the identical installation dimensions of its predecessor, the M6 135 allows direct replacement and upgrade without headstock modifications.
