Schaller M6 90 Guitar Tuning Machine

The Schaller M6 90 guitar tuning machine represents high precision and tuning comfort with its 1:18 gear ratio. All components are CNC-machined and surface-treated, featuring a self-locking drive mechanism that guarantees smooth, sensitive, and stable tuning.
Equipped with high-grade brass posts fitted into the housing, this tuning machine delivers maximum tuning stability and wear resistance. Closed housings are permanently lubricated with Schaller special grease, rendering them completely maintenance-free.
The innovative stepped M6 flanged washer eliminates the need for stepped peghead drilling, securing the string post reliably via the banjonut while removing tilt moments and reducing pressure on both the post and rear mounting screw.
