Don't hate. At worst I'm ambivalent on the SansAmp line. I've owned the BDDI and the programmable BDDI; I still kind of pine for the VT Bass.
Thing is, I think a lot of guys (myself included) looked to the Bass Driver as a stomp box to sit in front of their amp. This isn't its primary purpose. Its designed to send an "ampy" signal to the mixing board through its DI while sending an unaffected parallel signal to your amp. The end. Trying to use it for other purposes suits some players just fine--and others not so much. I'm the latter. But the engineer's face when I sent him the DI from the BDDI? He nearly died and went to heaven.
Maybe the VT bass is the way to go as an effect pedal: instant big-rig, retro rock sound. I don't think it's going to satisfy every distortion itch you're ever going to have. It doesn't scratch all of mine. But for that moment when you need to sound like John Paul Jones or John Entwhistle, I don't think there's another pedal on the market that does it better.
