Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets a high standard for closed tuning machines, featuring a precise 1:18 gear ratio for smooth and accurate tuning. High-precision CNC-machined components and a self-locking drive ensure velvet-smooth operation, sensitive adjustment, and consistent tuning stability.
Crafted with premium brass string posts fitted directly into the housing, this tuning machine provides maximum wear resistance and durability. The innovative stepped M6 flanged washer centers the string post securely over the banjo bolt, eliminating tilting moment and relieving stress on mounting hardware without requiring step-drilled headstock holes.
Permanently lubricated with Schaller special grease for maintenance-free performance, each tuner comes complete with banjo bolts, flanged washers, and mounting screws. The dual-pin design matches previous single-pin housing dimensions with a 0.39 in center-to-center pin spacing and 0.31 in post offset.
