Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers refined performance and unmatched tuning precision with its advanced 1:18 gear ratio. Continuing the legacy established by the original sealed M6 design in 1966, this upgraded model incorporates precision-engineered enhancements while maintaining its iconic aesthetic.
Every component is CNC-machined from premium materials, featuring high-grade brass string posts engineered for wear-free durability and maximum tuning stability. The self-locking internal drive mechanism and permanent factory lubrication with Schaller special grease ensure maintenance-free, ultra-smooth operation.
Equipped with an innovative stepped flanged washer measuring 0.39 inches in diameter, the M6 180 centers the string post securely through the threaded bushing without requiring stepped headstock drilling. This design eliminates tilting torque and distributes pressure evenly across both the post and the rear mounting screw.
