Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 Guitar Tuning Machine delivers state-of-the-art precision and exceptional tuning stability. Featuring an optimized 1:18 gear ratio, this closed-gear tuner ensures ultra-smooth, accurate, and reliable adjustments. Every component is CNC-machined to exacting tolerances and treated for a premium finish with self-locking drive mechanics.
Crafted with high-grade brass string posts, the M6 180 guarantees long-lasting wear resistance and robust performance. The innovative stepped M6 flanged washer centers the post automatically via the threaded bushing, eliminating tilting torque and removing strain from both the post and mounting screw without requiring stepped peghead drilling.
Permanently lubricated with Schaller special grease, these maintenance-free tuning machines offer smooth operation for a lifetime of playing. Designed to replace original M6 models directly without modification, they provide the ultimate upgrade in modern guitar hardware.
