Description
The D’Addario EPS190 ProSteels set splits the difference between the popular EPS220 and EPS170 gauges, giving long-scale bass players a rare middle ground: tension you can dig into for hours without fatigue, paired with the aggressive high-end bite steel players chase.
ProSteels earn their name from a specialized steel alloy that’s more magnetically responsive than standard roundwounds. The result is a brighter, more harmonically complex string that still delivers deep, tight low-frequency response — the classic “piano tone” that cuts through dense mixes whether you’re fingerstyle or picking hard.
This set covers a 40-100 gauge spread and is built for basses with scale lengths up to 36 1/2 inches, making it a solid fit for long-scale instruments that standard sets can’t quite reach.
