Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine features an improved 1:18 gear ratio that delivers exceptional precision and smooth, effortless tuning comfort. Setting the global benchmark for enclosed tuners since 1966, this updated design combines time-tested engineering with modern refinements.
Every component is CNC-machined to exact tolerances and surface-finished for lasting durability. The self-locking drive mechanism and high-grade brass string posts provide wear-free operation, maximum tuning stability, and velvet-smooth adjustments permanently lubricated with Schaller special grease.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post without requiring a stepped headstock bore. This design eliminates tilting torque and relieves mechanical stress from both the post and the rear mounting screw.
