Not that you really need it, but here are two more big thumbs up from me for the Bass Driver.
Now that I've gotten into recording I've found that it gets a great sound going direct to the recorder (used to be a Layla, now an HD24). I initially bought it for live use when I was playing in a metal band. I ran it in my effects loop for some overdrive, and also ran the XLR out to the board. Now in my new band (more of a heavy sludgier sound), I plug my bass (70s Gibson) into a Boss Bass Overdrive, and run that into the Bass Driver. The XLR out of the Bass Driver goes to the board, and the unaffected output goes to my cranked silverface Bassman through an Ampeg 8x10 to get my stage sound. I can tell you that I'm never more pleased than when I hear that sound pounding through the FOH mix and I can feel it shaking the room. I've had members of national acts that we've opened for ask me how I get such a great tone (their words, not mine).
I'd go so far as to say its probably the best thing I've ever bought for my bass setup. If only I could've done as well as my cousin when he bought a bass, amp, and Bass Driver for $75...
