Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine features a precise 1:18 gear ratio that delivers smooth, reliable tuning control. Originally introduced in 1966 as a benchmark for closed-type machine heads, this modernized model retains its classic character while incorporating advanced engineering refinements.
Precision CNC-machined components and high-grade brass string posts ensure optimal tuning stability and long-term wear resistance. The internal gearing is permanently lubricated with proprietary Schaller grease to ensure maintenance-free operation across years of use.
An innovative stepped collar washer aligns the string post securely through the threaded bushing without requiring stepped peghead holes. This design eliminates tilting torque and reduces physical stress on both the post and the rear mounting screw.
