I got these strings for a P-bass. They are very similar to D'Addario XLs (in fact they're manufactured by D'Addario for Fender) but with a bit more powerful low mids than the XLs. Which makes all the difference for me. I absoutely detest XLs but I kinda like these Fender 7250s once they're broken in. I don't particularly like their sound out of the box though. Like D'Addarios they sound very clanky. It's not that I don't like bright strings, it's just that these are bright in all the wrong places. Clank rather than crisp.
Once they're broken in (some would probably say dead...) I kinda like them though. They develop this "spongy" sound that I simply don't get with any other strings.
Definitely not my favourites (I prefer various types from Pyramid, TI and Rotosound) but their broken in sound offers something I enjoy on a P-bass.
They last reasonably long. Not the best, not the worst. Pretty much average in that regard. Which is ok with me as I prefer them kinda dead.
They're very cheap and pretty good strings on a budget. Certainly a lot better than certain ultra cheap "in house" brands I've tried.
These strings are also the stock strings on every Fender bass from Squier to Custom Shop so for a lot of people this is how an electric bass is supposed to sound. If you're one of those people these strings are of course an excellent choice. But for anyone willing to experiment: In my opinion there are far better bass strings out there.
