I'm not. Here's why.
When I first got the Axe-Fx II, I knew exactly what I was buying into - the list of available amps was easy to find online. I held out hope that, through the constant update process, we would see a small trickle of bass-related stuff get added. Surely, if they can spend these thousands of dollars every time for a few new amps, surely every few major firmware versions, we can get a single bass amp or bass effect added, right? Surely, even though we're the minority use-case, we still could get something. I even offered (many times now) to help anyway I could - from sending gear free of charge, to becoming a volunteer employee and doing the required work myself (which, I fully understand why FAS would not take that 2nd option, even if I did offer to sign any NDA or other agreement).
So, of course, I'd pour over every update with hope. And, of course, a ton of disappointment that "my people" we yet again, ignored and trivialized. Rinse and repeat for every firmware from 12 or so on.
After quite a few firmware releases now, it's become clear as day that FAS does not at all care for or pay attention to bass players. Once I resigned myself to that fact, I stopped caring what was in new firmwares, and as such, can no longer be disappointed in FAS. Sure, there's a couple of bass artists on the list, but that obviously hasn't bought us anything at all.
Eventually, maybe FAS will throw us a bone. I doubt it, and will be genuinely surprised if it ever manifests. The Helix is very tempting since they have included way more bass amps from factory, and do seem positioned to listen to input for more requests. A lot of people will say "But the Fractal products SOUND (or FEEL) better!" - well, that may be true, if you're a guitarist... since the Helix actually has bass gear in it, I can likely dial up better tone for me with the Helix. I'm waiting for a used one to pop up cheap and find out for myself. Yes, I'll keep my Axe-Fx II and will be buying an AX8 - but those will be used for guitar and mostly just expensive screwing around, if the Helix turns out to serve my needs better.
It's a good time to be a bass player - at least one modeling company out there seems to listen, and understand the importance of our instrument, and gives it at least a little bit of attention.
