If you get a Sansamp..which are you talking about? The bass driver IS a DI. I would track with that and then mult it. This is where I wish I had PT, because I would use the Sansamp plugin on that multed track. The sansamp plugin is not emulating the same sound as the BassDriver I dont think. I am going to try reamping through the bass driver though because I'd like to hear what it does. I would just have to tweak the knobs hard and get extreme with it.
