Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine sets a benchmark for closed tuners, featuring an upgraded 1:18 gear ratio for exceptionally precise and smooth tuning stability. All components are CNC-machined to exacting tolerances and treated with specialized permanent lubrication for entirely maintenance-free operation.
Equipped with high-grade brass posts precision-fitted into the housing, this tuning machine delivers dependable string centering, zero backlash, and maximum wear resistance. The self-locking drive ensures smooth, delicate, and solid pitch adjustment for any performance setting.
An innovative stepped M6 flanged washer reliably centers the string post without requiring stepped headstock drilling, eliminating tilt torque and protecting structural integrity during heavy use.
