Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers state-of-the-art precision and smooth tuning comfort with an upgraded 1:18 gear ratio. As the modern evolution of the legendary original closed tuner, it features CNC-machined components with a self-locking drive to ensure reliable, high-precision tuning stability.
Crafted with premium brass string posts fitted directly into the housing, these tuners eliminate play and prevent wear. Every unit is permanently lubricated with Schaller special grease for entirely maintenance-free operation across years of demanding use.
Featuring the innovative stepped M6 flanged washer, this tuner aligns the post automatically through the banjo bolt without requiring stepped headstock drilling. It shares identical mounting dimensions with its predecessor model, allowing seamless drop-in replacement on electric and acoustic guitars.
