Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a high standard for enclosed tuners, featuring an upgraded 1:18 gear ratio for velvety smooth and exceptionally precise tuning action. Every component is CNC-machined to exacting tolerances, complete with a self-locking drive and premium surface finishing that together guarantee lasting tuning stability and sensitive adjustment.
Built with solid brass string posts precisely seated within the housing, the M6 Pin delivers wear-free performance and superior resonance transfer. The specialized stepped M6 flanged washer centers the post reliably through the banjo bolt, eliminating tipping moments and taking structural pressure off both the post and mounting hardware without requiring stepped headstock drilling.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, these enclosed tuners utilize a dual-pin positioning layout with a 0.39 in (10 mm) pin-to-pin spacing and 0.31 in (8 mm) pin-to-post distance, making them ideal replacements and upgrades for modern guitars with pin-located headstocks.
