Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine series features a refined 1:18 gear ratio that provides exceptional precision and smooth, reliable tuning. Engineered with high-precision CNC-machined components and premium surface finishes, these tuners deliver seamless operation and long-lasting tuning stability.
Equipped with solid brass string posts precisely fitted into the housing, the M6 180 eliminates play and wear over extended use. The innovative stepped M6 flanged washer ensures straightforward installation and solid post centering via the hollow screw, reducing tilt moment and taking pressure off both the post and rear mounting screws.
Permanently lubricated with Schaller special grease for maintenance-free performance, the M6 180 directly replaces previous-generation models without headstock modifications, making it a dependable hardware upgrade for high-performance guitars.
