Thanks for the comments.
90db, my song in law who is a live sound engineer also commented on the massive power needed for the tour. Your link goes really well with the FOH video.
If you made it to near the end of the video, a 'learn more' caption popped up and redirected you to the Soundgrid website. There you learned the two extreme servers retail at $2490 each. Interestingly, when I first visited this site, it listed 4 models varying in price and features from $450 to the extreme at $2490. Today, the $450 model has been dropped from the lineup and only 3 models were listed, starting at $700.
The $450 would actually work quite well as a dedicated unit for a home studio and run 34 effects simultaneously.
In the most technical sense, at a 'live' Jason Aldean concert, we never actually get to hear how Jason really sounds live, only the processed Jason.
I frequent a site for pro sound & light people, some of whom mix the "A" grade acts. It's
mindblowing how much gear is used on a major tour these days! I remember the Grateful Dead's first tour, when I got to spend some time with them. They could put their entire system in a 22' U-Haul truck!
