I have great recordings with the My Mesa Express Tube Amp and "My tone" is super easy to get in room and recorded. I'm normally a low gain player. I can get my tone dialed in with a recording studio in 5-10 minutes, seriously. That's at local studio here i work with a bunch, as well as pro studio in Nashville. Virtualyl identical tone at each place, with minimal set-up and dialing in time.
But if i waver AT ALL from "that tone" it is tough to find the new tone in a relatively timely manner of speaking, and that is where I love the axe. I can get very good results in no time at all. And only limited in quality by my skill at tweaking the axe, not by the axe itself. Whereas with my tube amp, what it does it does fantastically, but that is basically all it does, one or two trick ponys, versus a basicalyl limitless ponies in the Axe
That said, i won't get rid of it, cause i love "that tone" that is in my opinion the perfect tone for my guitar, my fingers, my pedals, my tastes. But i don't always want that tone, and that plus the ease of transporting an axe, ease of getting new tones in studio, ease of switching tones in cover band, + about a million other things is why i bought Ultra, sold Ultra and am waiting for Axe II
