I have tried these on several types of basses and they are just in another league tonally. I've tried many different types of strings and they seem to just add a warmth anf thickness to any bass you play. I know some will complain about the cost but to me they are the best value on the market in terms of what they offer tonally and longevity wise. They are the smoothest string I've played with the exception of Tapes. Are there others out there that like them as good as I do?
