D’Addario Bass Guitar Strings, XL Pro Steels, EPS300, Long Scale, Custom Light Top/Medium Bottom Gauge 43-107, Tapered, 4-String

XL ProSteels are DAddarios brightest bass guitar strings. The unique, highly magnetic alloy in ProSteels delivers super-bright tone with magnified presence and attack. Made with a high carbon steel core and stainless steel wrap wire, ProSteels produce enhanced interaction with magnetic pickups, offering a palette of harmonically rich, brilliantly penetrating highs, combined with pronounced, tight-and-tough lows. This 43-107 Custom Light Top/Medium Bottom Tapered set is a D’Addario custom hybrid bass set optimized for PRS basses, with the unique gauge combination of .043 and .063 for the high strings and a tapered .085 and .107 for the low strings.
