Both the ampsims mentioned can get you a great sound if properly tweaked. The cabinet simulation is usable as well, but here are a few impulse sets of bass cabinets; a couple Ampeg 8x10's and an Eden 4x10. I have had these for years so I forgot where I got them from, all I know is they were free so I don't think I'm breaking any copyrights here.
I am tracking bass for an album on Wednesday.
If I remember I will make an IR of Harke VXL Bass Pre>Warwick Tubepath 5>Warwick 410 cab>421>API Mic Pre.
I don't know why I never did this because it would be great for guide tracks for me.
