Hello,
I believe that this topic was discussed here many times, but I'd like to ask about up-to-date feedback:
1) Preset switching lag. It was one thing that made some poeople prefer the Axe FX for live use
2) Booting time - axe fx in few seconds, Kemper nearly a minute (at least 30s was it?). Not a problem in studio or at the rehearsal, but when the electric shuts down for brief moment and then the gig must continue as soon as possible - 30s is killingly long time.
3) Two amps at the same time
4) Ultra Resolution cabinet IR's alternative
5) Tone Matching alternative for getting the exact sound from record or whatever..
Thanks
