D’Addario EPS220 offers more playing flexibility for players than a standard bass set while still maintaining the distinctive combination of biting high end, punchy lows, and super long life. It fits long scale basses with a string scale length of up to 36 7/8 inches. ProSteels are one of D'Addario's brightest and most corrosion-resistant strings. A specialized steel alloy delivers harmonically rich, brilliant high-end coupled with deep, tight lows that work in tandem to create the coveted "piano tone" steel players crave. Great for both articulate fingering and aggressive picking, ProSteels give you the extra edge and punch you need to cut through the mix. The super light gauge offers flexibility and ease of play without sacrificing tone. Made in the U.S.A. for the highest quality and performance. String gauges: wound .040, .060, .075, .095. Environmentally friendly, corrosion-resistant packaging ensures strings that are always fresh.
