Lovely tone and feel!
But the nuts or "donuts" at the bridge end of the strings are too small for my Fender Mustang PJ Bass! They go right through the bridge, so I have to use a small rod through the donuts to keep it in place. Not ideal, and I wish someone would have told me this. I have not noticed any tuning problems with the strings yet though, used them a couple of weeks now.
The thread at the bridge is also a little too long for my Mustang Bass, it goes over the saddle, but only by a little.
