Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers state-of-the-art precision and smooth operation, featuring an upgraded 1:18 gear ratio for exact, velvety tuning control. Setting the benchmark for enclosed machine heads since 1966, this updated design pairs classic legacy performance with contemporary engineering advancements.
Crafted with high-precision CNC machining and high-grade brass string posts, every component is engineered for maximum tuning stability, wear resistance, and long-term durability. Permanently lubricated with specialized Schaller grease, the self-locking drive ensures consistent performance without requiring routine maintenance.
An innovative stepped M6 flanged washer centers the string post perfectly via the banjo bolt, eliminating tilting friction and relieving pressure from the rear mounting screw. Designed for direct retrofitting without modification, it offers seamless installation and exceptional reliability.
