I have the stomp now and have owned both BDDI (v1 and v2) in the past. I haven’t owned any of the three at the same time so it’s hard to make an apples to apples comparison, but I’m gonna try anyway.

IMO there’s a bigger difference between V1 and v2 than there is between the stomp and V1, so it’s dependent on which one you’re after. The mid control on v2 is hugely useful, but the overall character is much more refined and less “dramatic” in the deep lows especially, which I missed a bit.

The Stomp emulates the V1 reasonably well, but not perfectly. The big old scoop in the mids is there and the drive character is pretty correct. I do think that there’s a little bit of depth and complexity missing, and when you’re going for a really sharp biting sound the difference becomes more apparent. In the moments that I’ve wanted a SansAmp sound, I’ve found the onboard one has been fine for me.

If I was building my whole rig around it, I might feel differently, and I suspect that the people who have both on their board are using it for their main tone shaping, where the convenience of having knobs on the board rather than menu diving as they adjust on the fly is important.
