Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 represents an advanced evolution of the legendary closed guitar tuner design. Engineered with a precise 1:18 gear ratio, it delivers velvety-smooth tuning action, exceptional accuracy, and uncompromising stability.
Every component is CNC-machined to exacting tolerances, featuring high-grade brass string posts and a self-locking drive mechanism. The innovative stepped M6 flanged collar reliably centers the string post and eliminates tilt without requiring stepped headstock drillings.
These sealed tuning machines come permanently lubricated with Schaller special grease for completely maintenance-free performance throughout their lifetime. Standard housing dimensions allow seamless drop-in replacement on existing instruments.
