I've been using these on my 5-string Jazz Bass. It came with them and I think they're the best. The E and B strings have much more fundamental and sustain than non-taper wound strings. They're bright and deep at the same time. It's almost like the low notes on a really good piano, and a little like the Greg Lake sound on the early ELP albums, but if you don't like that much brightness, just back off your tone control a bit. You might have to raise the B and E string saddles a little too, to compensate for the narrow taperwound part of the string. My bass strings through the body, so I got the 8250s.

The Fender 8250's came on my Hot-rodded P-Bass. But I thought I would put my preferred brand on when the factory strings from Fender got sloppy. After playing with the 8250's for a short while I got to be quite pleased with my open "E" ringing with clarity and sustain quite similar to a Steinway. More of these for me please.
