Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with a refined 1:18 gear ratio that ensures ultra-smooth and accurate tuning. Originally defining the benchmark for enclosed machine heads in 1966, this updated design integrates modern mechanical enhancements while maintaining its iconic aesthetic.
Crafted with premium CNC-machined components and high-grade brass posts, these tuners deliver unmatched tuning stability and wear-free operation. Every unit features a self-locking drive and is permanently lubricated with specialized Schaller grease for lifelong, maintenance-free performance.
Installation is streamlined via the innovative stepped M6 flanged washer, which centers the string post securely without requiring stepped peghead drilling. This mechanism prevents tilt moment and relieves mechanical stress from both the post and mounting hardware.
