Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 sets a high standard for closed guitar tuning machines, featuring a precise 1:18 gear ratio that ensures velvet-smooth, accurate tuning comfort. Every component is CNC-machined to exacting tolerances, surface-finished, and equipped with a self-locking drive mechanism to deliver uniform and stable tuning performance.
Crafted with premium brass string posts precisely fitted into the housing, these tuners guarantee exceptional tuning stability and long-lasting wear resistance. The innovative stepped M6 flanged washer ensures effortless mounting and reliable post centering without requiring stepped peghead counterbores, actively eliminating tilting moments and relieving mechanical stress.
Designed to match the original installation dimensions of its predecessor for seamless retrofitting, the sealed mechanism is permanently lubricated with Schaller special grease for completely maintenance-free operation.
