Regardless, the comparison is OX + a great tube amp. I sold my powered KPA and replaced it with OX and a Two Rock SP35 head. I already had the matching cab. It’s not even close. Real spring reverb, no scrolling through presets, no LEDs, unbelievable tone that you can twist a real knob and really change without worrying that you’re deviating from the profile too much, drop dead simple to use, and it takes fuzz ;-)
A couple of things here. I use and like the reverbs in the Axe FX, and the OX has presets as well. I'm not unhappy with the KPA necessarily. In fact, I'd love to be able to run it (and the Axe FX) into the OX via a Line In, but since that's not possible, my only other option would be to buy a real tube amp, which would give me the best of both worlds and allow me to run the KPA and Axe into the effects loop of the amp if I were so inclined.
