I have a Sansamp Bass Driver DI pedal and I use it alot. I agree that it can help a mediocre rig sound much better, and that's what I have been using it for lately. I jam with a buddy who has a big bass rig at his rehearsal space, but it's inherent tone sucks. The Bass Driver makes it tolerable, and now I don't have to lug my amp set-up every time I go there to play.
