It seems Fender's bass strings have been sometimes quite good, and then suddenly not so good. This was one of those sets that felt only so-so when you put them on. The tone was not "great", more like "this is OK". They also dulled out very quickly, losing both top end and sustain, and then developed "out-of-tune harmoics", making the bass sound out of tune or like through a Chorus pedal.
Considering that they are not very cheap, I can not recommend them. There are better strings for the same money, in my opinion.
