I have a passive dual humbucker bass (Steinberger Spirit 5 er) and a Roland Cube 60 watt with amp emulations and some effects, including drive I'm wondering if the Sans Amp Driver DI will bring anything to the table (like crunchy tube-itude) to that particular set of components. The drive on the Roland Cube can get nasty, but it's a very solid state sort of distortion. And the bass is one some people describe as that 'modern' sound. The issue there may have more to do with the high level of sustain with that bass -- combine that with the drive and it can easily sing for over a minute -- not exactly the grindy abrupt thump a lot of people expect. I really like the amp emulations on the Roland, I'm just looking for something to add a little more grind.
