Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed tuners with its refined 1:18 gear ratio, delivering velvet-smooth precision and exceptional tuning stability. Every component is CNC-machined to exact tolerances, surface-treated, and fitted with high-grade brass posts engineered for wear-free performance.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation while eliminating tilting torque. The stepped base seats securely within standard 0.39 in (10 mm) peghead bores without requiring stepped reaming, effectively relieving stress from the string post and rear fixing pins.
Designed with permanently lubricated, maintenance-free closed housing and dual positioning pins, the M6 Pin ensures stable, reliable string tension. It includes hollow screws, stepped washers, and mounting hardware for dependable long-term instrument upgrades.
