Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers exceptional precision and tuning comfort with an improved 1:18 gear ratio. All components are CNC-machined to precise tolerances and surface-finished, featuring a self-locking drive that delivers smooth, delicate, and stable tuning performance.
Crafted with high-grade brass string posts fitted accurately into the housing, these tuners ensure maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer guarantees effortless mounting and permanent centering of the string post without requiring stepped headstock drilling.
Designed with closed housing construction, each tuner is permanently lubricated with Schaller special grease for completely maintenance-free operation. The M6 135 shares identical installation dimensions with previous generations for direct replacement without instrument modifications.
