For the AX8, I used both the front panel and the editor, but I would say about 75 percent of the time I used the editor, although I was pretty comfortable with the panel. For the Helix, I almost exclusively use the front panel. So far I have only used the editor for loading IRs. I feel like I am pretty open minded. I have also owned a free standing recording studio in the past. I mention this because some people forget what guitar sounds like solo'd and dry, and not in a mix with board EQ and effects. Pretty much all of the big four (Fractal, Helix, Amplifire, and Kemper) can replicate what a recorded guitar sounds like while rising above the threshold for "sounding real". I imagine the Headrush unit can too. I know from working with bands during recording sessions that A/Bing tones is influenced heavily by volume, then EQ, and then basic tone IMHO. Again, I mention to this to say you can get it done with what's out there. Kemper: I have not personally tried one, and I don't want to, because I am afraid I will want it! I recently saw/heard this video. It was posted in response to someone on the forum who was asking if modelers could replicate his (very awesome sounding) plexi. Man that sounds awesome. Hope my Helix can do this! I do actually use a plexi model on the Helix for a "near clean" or as I call it my "grit" patch. Again, I am blessed in that I was able to sit down and do in-room comparisons between the AX8, Helix, and Amplifire. For me, factoring in work flow, tones, functionality, and price, the Helix was the clear winner. I could absolutely however make cases for picking each of the other devices. They are all awesome.
