Overview
A silk and steel core under silver-plated copper windings defines these D'Addario strings, built to be the warmest and mellowest in the line. The result is a softened tone that folk players often favor.
Low tension and less finger noise make this set a good match for mellow acoustic styles. It targets parlor guitars and older instruments where heavy tension would be a risk. The gauge appears only in the title.
Who it's for
Players with delicate or older instruments who want a gentle feel and a quiet surface. Anyone who strums hard and wants brightness should choose a bronze set.
Pros and cons
- Warm, mellow tone

Performance notes
Silk fibers in the core soften the vibration, and the silver-plated copper winding adds a rounded top end. Lower tension means less pull on the top, which is why the set is aimed at vintage and parlor builds. The listing marks the coating as coated, with no further detail.
