The D'Addario ECB81-5 XL Chromes are the five-string version of D'Addario's best-selling flatwound bass guitar strings, famous for their warm, mellow tone and silky smooth feel. They deliver the deep, damped low-end character that only quality flatwounds can produce. Each string is wound with flattened stainless steel ribbon wire that is polished to an exceptionally smooth surface, eliminating finger squeak across the fretboard while producing a round, full low end with plenty of punch. The set adds a .132 low B for extended range, making Chromes a favourite among jazz, R&B and pop bassists, and a great match for players chasing an upright-like thump on electric bass. The set fits long-scale basses with string scale lengths up to 36 1/4 inches, and every set is manufactured in the U.S.A. on digitally controlled machinery for unmatched consistency, set after set. Whether you play smooth gospel sessions, jazz gigs or studio work in Nairobi, these strings give your five-string bass a refined vintage voice.
