Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark for closed tuners, featuring an upgraded 1:18 gear ratio for smooth, accurate, and stable tuning performance. Engineered to fit the identical installation dimensions of its classic predecessor, it enables seamless replacement without modification.
Precision CNC-machined components and high-grade brass string posts guarantee maximum tuning stability and wear-free operation. Internal mechanisms are permanently lubricated with Schaller special grease, providing an entirely maintenance-free enclosed design.
An innovative stepped M6 flanged washer centers the string post reliably through the banjonut, eliminating tilting torque, protecting mounting screws, and removing the need for stepped peghead holes.
