Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 Guitar Tuning Machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. CNC-machined components and a self-locking drive mechanism ensure stable, precise performance and extended longevity for electric and acoustic guitars.
Equipped with high-grade brass string posts and permanently lubricated with Schaller special grease, these sealed tuning machines offer completely maintenance-free reliability. The innovative stepped M6 flanged washer reliably centers the string post and eliminates tilt torque without requiring a stepped headstock bore.
Designed as a direct replacement for legacy M6 tuners, the M6 180 installs without headstock modifications. Each set includes hollow threaded screws, step washers, and mounting screws for a complete and secure installation.
