I recently got me the Bass&Drum-card. And the basses are really good. They have more punch and realism that I've ever heard before. There are also a lot of nice bass-effects&noises (like pick-up slides etc.) The fretless-solo sounds are some real killers!!! When it comes to the drums, I'm not so sure, but they much better than the internal ones in my JV-2080. For sequencing, this card is a must for JV-owners...

Good luck!!
