I used to have an all solid state rig and bought a BDDI to give me some "tubeness" once in a while. I now have an Eden WT-550 head (which I love) and it has the tube pre so I find that I don't really need the BDDI any more. I use the Eden DI which I also like - although it would be nice if it had a pre/post eq for the DI but not that big a deal for me. I have used it on occasion for that "SVT" setting when I'm playing rock. Most of my gigs are jazz or singer/songwriter type gigs so I don't need that "overdriven" tone much. Just curious what others do with their BDDI? Is it more of an effect or a "vital" part of your sound?
