Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine features a precise 1:18 gear ratio that delivers exceptional accuracy and smooth tuning stability. All parts are precision CNC-machined and surface-treated, utilizing a self-locking drive to provide consistent, backlash-free operation.
Equipped with high-grade brass string posts engineered to fit seamlessly inside the housing, these tuners ensure reliable wear resistance. The innovative stepped M6 flanged washer centers the post automatically through the banjo bolt, eliminating the need for step-drilled headstock holes while reducing mechanical stress.
Permanently lubricated with Schaller special grease, these sealed tuners are entirely maintenance-free. Designed for direct retrofitting without modification, they offer dependable performance for modern and vintage instruments alike.
