Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets a high standard for closed tuning machines, featuring a precise 1:18 gear ratio for velvety smooth and accurate tuning comfort. High-precision CNC-machined components with a self-locking drive ensure consistent, delicate, and stable tuning performance across all playing conditions.
Crafted with premium brass string posts precision-fitted directly into the housing, these tuners deliver maximum tuning stability and long-lasting wear resistance. Every closed unit comes permanently lubricated with Schaller special grease, making the entire mechanism completely maintenance-free over its lifespan.
The innovative stepped M6 flanged washer centers the string post reliably via the hollow screw, eliminating tilting torque and reducing pressure on both the post and rear mounting screw. With slightly optimized housing dimensions, it easily replaces older original M6 models without requiring headstock modifications.
