D'Addario EPBB170 Phosphor Bronze Acoustic Bass Guitar Strings - 45-100 offer a warm, well balanced acoustic tone, with bright intonation and a "fret-friendly" round wound feel that made them D'Addario's most popular acoustic guitar strings. D'Addario received worldwide acclaim in 1974 for introducing Phosphor Bronze to string making, giving their strings such superb, long-lasting tone.

All D'Addario strings are precisely wound around a hexagonally shaped high-carbon-steel core wire by computer-controlled machines guaranteeing clear intonation, rock-solid fundamentals, and incomparable consistency in every string. The tight core tension produced through this rigorous quality-controlled process results in a harmonically rich, longer-lasting string.
