Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and refined performance, setting a benchmark for enclosed tuners with its smooth 1:18 gear ratio. Every component is CNC-machined and finished for dependable, micro-fine tuning stability and long-lasting operation.
Featuring high-grade brass string posts precisely seated within the housing, this tuning machine delivers wear-free performance and superior tuning retention. The innovative stepped M6 flanged washer reliably centers the string post over the threaded bushing, eliminating tilt torque and the need for a stepped peghead hole.
Sharing identical mounting dimensions with its predecessor model, the M6 135 allows direct replacement without instrument modifications. All enclosed internal mechanisms are permanently lubricated with specialized Schaller grease for completely maintenance-free functionality.
