Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 represents the evolution of the legendary original closed tuning machine introduced in 1966. Engineered with an upgraded 1:18 gear ratio, it provides unmatched precision, smooth operation, and superior tuning comfort for electric and acoustic guitars.
Every component is precision CNC-machined and surface-treated, featuring a self-locking drive and high-grade brass string posts fitted tightly into the housing to guarantee maximum tuning stability and long-lasting wear resistance. Permanent lubrication with Schaller specialty grease ensures completely maintenance-free performance.
The innovative stepped M6 flanged washer centers the string post perfectly via the banjo bolt without requiring a stepped headstock bore. This design eliminates tilting torque and reduces mechanical strain on both the post and the rear mounting screw for flawless reliability.
