Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine represents high precision and advanced engineering, featuring an upgraded 1:18 gear ratio for smooth, accurate tuning. CNC-machined components and high-grade brass posts ensure lasting tuning stability, sensitive response, and wear-free performance.
Equipped with the innovative stepped M6 flanged washer, this machine head centers the string post securely through the banjo bolt without requiring a stepped headstock bore. This design eliminates tilting torque and relieves pressure from both the post and rear mounting screw.
Featuring permanently lubricated internal gears with Schaller special grease, the enclosed housing provides entirely maintenance-free operation. Built to identical mounting dimensions as its predecessor, it serves as a seamless drop-in replacement for effortless guitar upgrades.
