Tried it with my bass last night, both on the studio preamp setting and some of the amph settings. Works great!

So the scorecard so far is that it works extraordinarily well on clean amph settings and with my bass. To me, the heavy gain tones leave something to be desired. I'm going to try recording with it and see if how it sounds that way. The issue might be with my headphones, but I don't have anything to compare them with right now.
