Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed tuners, featuring an upgraded 1:18 gear ratio for smooth, precise, and responsive tuning. Engineered with CNC-machined components and self-locking drive mechanisms, it delivers exceptional stability and long-lasting performance.
Crafted with premium brass string posts fitted directly into the housing, this tuning machine provides maximum wear resistance and pitch stability. The stepped M6 flanged washer centers the post securely through the hollow screw, preventing tilting and eliminating the need for stepped peghead boreholes.
Permanently lubricated with specialized grease, the sealed housing ensures maintenance-free operation. Designed to match standard vintage dimensions, it allows for direct drop-in replacement on compatible headstocks without requiring body modifications.
