Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents high-precision engineering with an advanced 1:18 gear ratio for smooth, velvety, and exact tuning control. Built on the legacy of the original 1966 closed-housing design, this updated model integrates modern innovations while preserving its iconic aesthetic.
Every component is CNC-machined to precise tolerances and surface-finished for maximum wear resistance, featuring premium brass posts accurately seated inside the housing. The self-locking drive and Schaller special permanent lubrication guarantee reliable tuning stability and completely maintenance-free operation.
Featuring the innovative stepped M6 flanged washer with a 0.39 in (10 mm) base diameter, this design self-centers the string post reliably without requiring a stepped headstock bore. This eliminates tilt torque and relieves mechanical stress from both the post and mounting screws for enhanced longevity.
