I only tried them briefly last night at rehearsal. We had other things that I had to really focus on, so working with new cabs and tweaking presets was pretty low on the priority list sadly.
My initial impressions are overall good though. Of the bunch I (very quickly) tried, the 410t stood out the most. I got to spend maybe 15 or 20 minutes total with these so far though, so not nearly enough time. Monday I hope to get more time to sit down with them.
For what its worth, I'll gladly buck up and buy pretty much any bass cab packs that come out. I skipped the ML one as the clips I heard of it were pretty dang weak sounding (and we already have the Ampeg 4x10 in the box).
I too hope it shows Fractal that there is interest in legitimate, high quality, and variety of bass gear. I, am not really holding my breath on much changing, though. There are other cabs that I'd like to see, that I hope 3Sigma and Dr.Bonkers can pick up and make good IRs of for us. We're at the mercy of FAS, and just have to see where they go. I'm certain bass is an extremely low priority for them still.
