Personally I like using a pedalboard because I route all the cabling to a jack panel on the board, so I'm not constantly plugging/unplugging anything from the ax8 itself. I'm also a weird one that kind of likes having a bit of extra angle & height to the ax8, I see a lot of people complaining about that with the ax8 on boards like a pedaltrain or similar. I know that plopping an ev-1 and an ax8 on the ground, plugging in two or three audio cables, power, and 1 trs patch is really no big deal at all...but I just really like plopping the board down, plugging my power & 2 or 3 1/4" cables to the side of it and being done. Its also easier to then slide it around the rehearsal space if I need to move positions or whatever (actually does happen often enough to be a thing for me)
I just feel like its easier to deal with, less wear & tear on the devices, less risk to the devices (tripping over a cable only hits the board, not the ax8) etc etc.
I'm using a templeaudio duo24. Its basically just big enough for the ax8/ev1, MIGHT be able to squeeze one more mini pedal of some sort on there. But it weighs like a pound, light as a feather. Just need to get the bag to go with it, right now it just gets placed in the trunk of my suv to move from a to b. Don't have any great pictures at the moment but I can get some, you can also find other user's pictures of a similar setup on the forum by searching for duo24 or whatever.
