Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine features a precise 1:18 gear ratio that delivers smooth, velvet-like tuning feel and unmatched stability. Engineered with high-precision CNC manufacturing and surface finishing, every component works seamlessly with a self-locking drive for consistent and delicate adjustments.
Crafted with premium brass string posts precisely fitted into the housing, this machine head offers maximum tuning stability and wear resistance. Closed housings are permanently lubricated with proprietary Schaller grease, providing completely maintenance-free operation over its lifespan.
The innovative stepped M6 flanged collar facilitates quick installation while securely centering the string post via the hollow bolt, eliminating the need for a stepped headstock bore. This thoughtful engineering reduces tipping moment and relieves direct pressure on both the post and the rear mounting screw.
