The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. All components are CNC-machined and surface-treated to guarantee smooth, sensitive, and stable tuning through its self-locking drive mechanism.
Crafted with premium brass string posts precisely fitted into the housing, this closed tuner provides maximum tuning stability and wear-free operation. Permanent internal lubrication with Schaller special grease ensures complete, maintenance-free longevity.
Featuring the innovative stepped M6 flanged washer, it centers the string post securely through the hollow screw without requiring stepped headstock holes. Sharing identical installation dimensions with its predecessor, it offers effortless direct replacement.
