Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets a benchmark for closed tuners, featuring an advanced 1:18 gear ratio that provides velvety smooth operation and precise tuning accuracy. All internal and external components are CNC-machined to exacting tolerances and treated with a durable surface finish, driven by a self-locking mechanism for maximum tuning stability.
Equipped with solid brass posts precisely fitted into the housing, each unit delivers wear-free performance under continuous string tension. The innovative stepped M6 flanged washer centers the string post securely through the hollow screw, removing tilt torque and eliminating the need for stepped headstock drilling.
Permanently lubricated with Schaller special grease, these tuners are fully maintenance-free and engineered for effortless replacement on standard headstocks without requiring permanent modifications.
