Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and legendary performance for demanding players. Built with an optimized 1:18 gear ratio, it provides exceptionally smooth, velvet-like operation and pinpoint tuning accuracy.
Crafted with premium high-grade brass string posts and CNC-machined components, each unit features a self-locking drive mechanism that guarantees maximum tuning stability and long-lasting durability. The sealed housing is permanently lubricated with proprietary Schaller grease for entirely maintenance-free service.
Featuring the innovative stepped M6 flanged washer with a 0.39-inch diameter base, the assembly eliminates tilt torque and relieves mechanical stress on both the string post and rear fixing screw. It matches the exact installation footprint of classic predecessor models for effortless replacement.
