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 legendary closed-gear tuner ensures ultra-smooth, responsive, and reliable operation across all playing styles.
Crafted with precision CNC-machined components and high-grade brass string posts, the M6 180 offers wear-free performance and superior longevity. Every unit is permanently lubricated with Schaller special grease for entirely maintenance-free service.
Installation is streamlined thanks to the innovative stepped M6 flanged washer, which centers the string post without requiring a stepped peghead bore. This design eliminates tilting torque and protects both the post and mounting screw from excessive mechanical strain.
