Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets a high standard for closed guitar tuning machines with an improved 1:18 gear ratio that ensures velvet-smooth and precise tuning performance. All components are high-precision CNC-machined and surface-treated to guarantee smooth, sensitive, and stable operation through a self-locking drive.
Crafted with premium brass string posts precisely fitted into the housing, these tuners deliver maximum tuning stability and wear-free longevity. Each enclosed tuning machine is permanently lubricated with Schaller special grease for completely maintenance-free operation.
Featuring the innovative stepped M6 flanged washer, this design facilitates effortless installation and permanently solid post centering via the banjo bolt. This engineering eliminates tilting moment and absorbs mechanical pressure from both the post and rear mounting screw without requiring stepped headstock drilling.
