Independent shopping perspective
Use the D'Addario XS Plain Steel .009 single when you want to select that individual string rather than buy a fixed assortment. It is suited to adding one chosen string to an existing setup or assembling a custom combination from separate singles. Made in the USA, it uses high-carbon steel, corrosion-resistant wrap wire, and computer-controlled precision winding. The XS series is designed for aggressive playing while maintaining tuning and intonation.
