Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 series guitar tuning machine sets an industry benchmark for precision, tuning comfort, and lasting reliability. Engineered with an optimized 1:18 gear ratio, this closed tuning machine delivers smooth, delicate, and ultra-precise tuning response. Each component is CNC-machined to exact tolerances, surface-treated, and permanently lubricated with Schaller special grease for entirely maintenance-free operation.
Solid brass string posts are fitted into the housing to ensure optimal mechanical alignment, maximum tuning stability, and wear-free longevity. The self-locking drive maintains exact string tension without slipping during vigorous play. The innovative stepped M6 flanged collar reliably centers the string post through the headstock counter-bearing hole without requiring stepped reaming, reducing tilting torque and relieving lateral stress from both the post and mounting screw.
Designed to drop directly into standard mounting holes without headstock modifications, the M6 180 is compatible as an upgrade or direct replacement for legacy installations. Its rugged enclosed metal construction shields the gearing from dust, moisture, and wear, ensuring exceptional performance on stage and in the studio.
