ProSteels are one of D'Addario's brightest and most corrosion resistant strings. A specialised 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. The EPS170S set is the short scale version of D'Addario's best-selling ProSteels bass set and the standard gauge for most electric basses. It offers the ideal combination of biting high end, punchy lows and super long life. For use on short scale basses with a string scale length of up to 32 inches.

Like all D'Addario strings, this set comes in environmentally friendly, corrosion resistant packaging for strings that are always fresh, and are made in the U.S.A. for the highest quality and performance.
