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.
