Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets an industry benchmark for closed-type tuners, combining legendary heritage with refined German engineering. Built with a precise 1:18 gear ratio, it ensures velvet-smooth operation, highly accurate tuning control, and rock-solid pitch stability across all playing conditions.
Every component is precision CNC-machined and surface-treated for maximum durability, utilizing high-grade brass string posts that fit snugly into the housing to prevent wear. The internal closed mechanism is permanently lubricated with Schaller special grease, providing completely maintenance-free performance throughout its lifespan.
Featuring the innovative stepped M6 flanged washer, this tuner guarantees straightforward installation and reliable centering of the post without requiring stepped headstock boreholes. It retrofits seamlessly into existing instruments while eliminating tilting torque and reducing mechanical stress on mounting screws.
