Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine series sets a legendary benchmark in closed guitar tuners, featuring an advanced 1:18 gear ratio for unmatched tuning precision and silky-smooth action. Each tuner is CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for maintenance-free operation and high tuning stability.
Equipped with high-grade brass posts, these tuners minimize wear and ensure dependable pitch retention under demanding playing conditions. The innovative stepped M6 flanged washer eliminates tilting torque and self-centers the string post securely through the hollow screw, removing the need for stepped headstock drill holes.
Engineered for effortless replacement, the M6 180 installs seamlessly into existing configurations without requiring headstock modifications. Every set provides a secure, self-locking drive and solid mechanical seating for reliable, sensitive adjustments.
