Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine features a precise 1:18 gear ratio that delivers exceptional tuning stability and smooth, velvet-like operation. Every component is CNC-machined with high precision and surface-treated to guarantee smooth, sensitive, and reliable tuning across all playing conditions.
Equipped with premium brass string posts precisely fitted into the housing, this machine head minimizes wear while maximizing tuning retention. The innovative stepped M6 collar washer ensures straightforward installation and durable centering of the post without requiring a stepped headstock bore.
Permanently lubricated with Schaller special grease, the sealed housing provides completely maintenance-free performance. Designed to replace previous models directly without instrument modification, it offers modern engineering while preserving classic styling.
