Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 series sets the standard for closed guitar tuning machines, featuring a precise 1:18 gear ratio that delivers velvet-smooth operation and unmatched tuning accuracy. High-precision CNC-machined components with self-locking drives ensure stable, sensitive adjustments with zero maintenance thanks to Schaller special grease permanent lubrication.
Engineered for maximum reliability, every string post is crafted from premium brass and seated precisely within the housing to eliminate wear and ensure optimal tuning stability. The innovative stepped M6 flanged washer centers the string post securely without requiring stepped headstock boreholes, taking lateral pressure off the post and mounting screws.
Designed as a drop-in replacement for earlier M6 models without modifications, these tuners seamlessly blend legendary legacy design with modern precision engineering. High-grade metal, perloid, and ebony button options alongside standard or locking post configurations cater to demanding musicians and luthiers alike.
