Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine sets a benchmark for closed-type tuners, engineered with a precise 1:18 gear ratio for exceptionally smooth, fine-tuned, and stable pitch adjustment. Each component is precision CNC-machined and surface-treated, featuring a self-locking drive mechanism that guarantees consistent tuning performance across all playing conditions.
Crafted with premium high-grade brass string posts, these tuners fit tightly into the housing to eliminate play and maximize long-term wear resistance. Every closed unit is permanently lubricated with proprietary Schaller special grease, rendering the internal mechanism completely maintenance-free throughout its service life.
Installation is streamlined via the innovative stepped M6 flanged washer, which centers the string post securely through the banjo bolt without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical strain on both the string post and rear mounting screws for enhanced reliability.
