Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers high-precision guitar tuning with an advanced 1:18 gear ratio for smooth, accurate operation. Built upon the legacy of the original closed tuning machine established in 1966, this updated design incorporates refined engineering for modern performance demands.
Each component is CNC-machined from premium materials, featuring precision-fitted brass string posts that provide maximum tuning stability and wear resistance. The self-locking drive and permanent internal lubrication with Schaller special grease ensure maintenance-free, uniform operation over an extended lifespan.
Installation is streamlined through the stepped M6 collar washer, which reliably centers the string post through the threaded bushing without requiring stepped headstock drilling. This innovative design eliminates tilting moments and relieves mechanical stress on both the post and mounting screws.
