Our staff at BCR Music & Sound are all professional musicians, so we love legacy companies like D'addario.  They exemplify quality across the board on their strings, cables, and other guitar accessories. The nickel wound XL Series guitar and bass strings and phosphor bronze acoustic string all sound fantastic and are super reliable.  When you need that extra durability, we recommend the amazing NYXL Series strings, which bolster a high-carbon steel core and plain steel alloy.
