Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets an exceptional standard for closed tuning machines, featuring a precise 1:18 gear ratio that ensures velvet-smooth and accurate guitar tuning. Every component is CNC-machined to high tolerances, surface-finished, and equipped with a self-locking drive for lasting tuning stability.
Crafted from premium brass, the string posts fit precisely into the housing to guarantee wear-free performance. The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped peghead bore, eliminating tilting torque and protecting mounting hardware.
Permanently lubricated with Schaller special grease, these sealed tuners remain completely maintenance-free. Designed for direct replacement of predecessor models, they provide robust performance and flawless functionality across a wide range of headstock configurations.
