Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. All components are CNC-machined to exacting tolerances and surface-finished, utilizing a self-locking drive mechanism that guarantees smooth, velvet-soft, and highly stable operation.
Equipped with high-grade brass string posts engineered for wear-free durability, each unit is permanently lubricated with Schaller special grease to remain entirely maintenance-free over its lifetime. The innovative stepped M6 flanged washer reliably centers the post without requiring a stepped peghead bore, eliminating tilting torque and reducing mechanical stress.
Designed to fit modern and vintage instruments, the M6 180 can replace original M6 tuners directly without headstock modifications. Premium materials and German engineering make this tuning machine a reliable choice for professional guitarists seeking peak tuning stability.
