Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents the refined evolution of a legendary closed-gear design, offering unmatched precision and exceptional tuning comfort. Engineered with an upgraded 1:18 gear ratio, it delivers smooth, sensitive, and velvet-like response across all strings. High-precision CNC machining and premium brass string posts ensure superior structural integrity, maximum tuning stability, and completely wear-free operation.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post via the banjo bolt. This eliminates the need for stepped peghead holes while effectively absorbing mechanical tilt and relieving pressure from the post and mounting screw. Every sealed enclosure is permanently lubricated with Schaller special grease for entirely maintenance-free reliability.
With housing dimensions optimized for seamless replacement of previous generations without modifications, the M6 180 integrates effortlessly onto your instrument. The self-locking drive and meticulously finished components provide rock-solid pitch retention for professional performance.
