Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding tuning precision and velvet-smooth operation with its improved 1:18 gear ratio. All components are CNC-machined to precise tolerances and surface-finished, featuring a self-locking drive mechanism that guarantees consistent, sensitive, and stable tuning.
Equipped with high-grade brass posts precisely fitted into the housing, this tuning machine provides maximum tuning stability and wear resistance. Closed housings are permanently lubricated with specialized Schaller grease, making the unit completely maintenance-free.
The innovative stepped M6 flanged washer centers the string post reliably via the banjo bolt, eliminating tilting moment and relieving stress from both the post and rear mounting screw without requiring stepped headstock boreholes.
