DR’s new Pure Blues bass guitar strings are wound with an exclusive, new Quantum-Nickel alloy for a fat, warm punch and a smoother feel. This new material, wound by hand to the highest possible standards, gives these strings an amazing low end, enhanced mids, tons of punch and bright clear highs. The round core allows increased flexibility over other hex core strings. Hand winding allows DR’s accomplished string winders to make micro corrections during winding that even a computer assisted, machine string winder cannot. DR says, “The Best of Steel with Nickel Feel!” Available in four 4-string, two 5-string and one 6-string sets.
