Thanks for this video. I struggled with this issue a lot in my life and not that I want to re-enter this debate but saying things like "room sound don't matter" is totally disingenuous. In small venues like your typical bar, part of the sound comes from the stage. In small rehearsal rooms, people will also feel right away if you go direct versus using an amp. There is this one time where I got a gig because the guy before me went direct at rehearsal and I used a shitty, tiny combo amp - the gut instinct of the band was to choose me over the other guy because I "sounded amazing" in comparison - little did they know, his modeller was a better rig than mine for 90% of other situations outside of this particular small room rehearsal. Similarly, I've brought the Kemper to a in-house rehearsal with an artist and we had to have a talk about "my flat sound". While it's tempting to make absolute statements like "room sound don't matter" because it would make life so much easier, the truth is that there are many types of sonic environments and you have to know for yourself when the positives of a modeller are going to outweigh those of a pedalboard + amp or vice-versa.
These days, I use the pedalboard and backline amps more and more for live work, I feel I get better control over variables. My last few rehearsals with the Kemper or the Axe were especially frustrating and I wholeheartedly resent having to deep dive into endless menus while trying to make music at the same time.
