• XL Chromes are a flat wound electric bass string, which provide a mellower tone than round wound strings. • Chromes stainless steel flattened ribbon wrap wire is precisely polished for unparalleled smoothness and a dark, yet warm tone. • Like all D’Addario bass strings, XL Chromes are made with our proprietary Hex-Core, ensuring perfect intonation, consistent feel, and reliable durability. | • Chromes sets have a code on the recyclable VCI bag, which you can register to earn Players Circle points. • D’Addario bass guitar strings are made in the USA—drawn to our exacting specifications at our New York production facility. |
