The Ernie Ball Slinky Paradigm Acoustic guitar strings provide unprecedented strength and longer lifespan while maintaining 100% of the classic tone and Earthwood feel. The high-quality and extremely durable steel of Ernie Ball is included in both the wound and plain strings, along with a patented reinforcement at the end of each plain string's ball-end. This ensures superior resistance to tension and wear, strings that tune quickly and maintain their tuning under the most adverse conditions and strong playing styles. 

The combination of Everlast nano-treatment by Ernie Ball, with reinforced plasma wire wrapping, provides additional resistance to corrosion and reduced accumulation of debris within the string's winding, resulting in minimal sound loss.
