Newer isn"t always the same as better — ask any blues cat and they"ll tell you that the same 12 bars have been doing the trick for a good long while. And just like the blues, DR"s Pure Blue strings rely on a time-tested, traditional method to bring out the soul of the music. Each old-style Pure Blue string has a smooth round core, and they"re only wrapped in pure nickel. Sure, it"s a slow and painstaking process, but DR knows it"s worth it. After all, you"re not going to get the cool vibe and lingering sustain of a set of Pure Blues from just any strings.
