Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine represents the evolution of an industry-standard closed tuning machine, featuring an enhanced 1:18 gear ratio for exceptionally precise and smooth tuning. Every component is CNC-machined and finished to high tolerances, utilizing a self-locking drive mechanism to deliver optimal tuning stability and sensitivity.
Equipped with high-grade brass string posts engineered directly into the housing, this machine head prevents wear and ensures maximum durability. The innovative stepped M6 flanged washer centers the string post securely via the threaded bushing, eliminating tilting torque and reducing mechanical stress on the housing and mounting screws without requiring stepped headstock holes.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, the M6 180 directly replaces older M6 models without headstock modifications. This tuning machine combines advanced German engineering with reliable mechanical locking options for superior instrument performance.
