Amazing tone for the low cost.
My former set of strings were Warwick Red Labels, and I thought they sounded good. Were a bit sloppy in feel, and they got old, so I changed to D'addario XL (my other bass had them and I liked them on that one).
It was one of the best things I've done in my life.

XL's are real jummyfish for low price. Very nice strings.
