Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark for enclosed tuning mechanisms, featuring a refined 1:18 gear ratio for velvety smooth and precise tuning accuracy. Built with CNC-machined components and self-locking drive mechanics, it ensures consistent operation, maximum tuning stability, and zero maintenance thanks to permanent lubrication with Schaller special grease.
Crafted with premium high-grade brass string posts engineered precisely into the housing, this tuning machine eliminates wear and provides long-lasting reliability. The innovative stepped M6 flanged washer reliably centers the string post via the threaded bushing, effectively removing tilting torque and distributing pressure evenly without requiring stepped peghead bore holes.
Featuring the exact installation dimensions of its classic predecessor, the M6 135 allows direct, modification-free retrofitting on standard guitar headstocks. Each unit combines precision German engineering with robust construction to deliver peak performance and tuning security for discerning musicians.
