Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 represents precision engineering and refined performance, building upon the legendary legacy established by the original enclosed tuner. Featuring an enhanced 1:18 gear ratio, it provides exceptionally smooth tuning, precise micro-adjustments, and steadfast stability. Each component is CNC-machined to exacting tolerances and treated with a high-grade surface finish for reliable, wear-free operation.
Equipped with premium brass string posts fitted directly into the housing, this tuning machine eliminates unwanted play and ensures long-lasting durability. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring stepped headstock drilling. This design absorbs lateral tension, eliminating tipping moments and protecting the rear mounting screw from mechanical stress.
Permanently lubricated with Schaller special grease, all internal gearing remains completely maintenance-free over years of performance. The M6 180 easily retrofits earlier enclosed models without modification, delivering modern precision to classic and contemporary headstocks alike.
