Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio for smooth, sensitive, and accurate tuning. CNC-machined components with a self-locking drive mechanism ensure dependable performance, while high-grade brass string posts provide exceptional tuning stability and long-term wear resistance.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped headstock bore. This specialized design eliminates tilting moments and relieves mechanical pressure from both the post and the rear mounting screw.
All enclosed machine heads are permanently lubricated with Schaller special grease, rendering the internal mechanism completely maintenance-free. Designed to drop in as a direct replacement for standard enclosed tuners, it provides modern performance enhancements while preserving classic aesthetic appeal.
