Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an optimized 1:18 gear ratio. As an evolution of the industry standard enclosed tuner first introduced in 1966, this model incorporates refined mechanics and robust performance for modern instruments.
Precision CNC-machined components and high-grade brass string posts ensure superior tuning stability and wear-free operation. The self-locking drive mechanism provides consistent, sensitive response, while factory lubrication with specialized grease guarantees maintenance-free performance.
Featuring the innovative stepped M6 flanged collar, this tuning machine automatically centers the string post without requiring stepped peghead holes. This design eliminates tilting torque and protects both the internal post and mounting screw from unnecessary strain.
