I use this set of strings with my Viper ltd-1000 with emg 57/66s and unlike some tone purists, I really enjoy the feel and sound of these strings. (Maybe I use them more for heavy music.) I tried the xt coated series from d’addario (I know, they market them as lightly coated for the sake of tone etc.), and they’re cool but tend to wear just a bit better than regulars. So I’d put my money on nyxl if I went with d’addario with my lp. Anyway, whenever I go with drop C tuning, I lean toward elixirs. Besides, if you have several guitars, they’re a huge money saver too.
