Where you are coming from seems to be your usual place of believing that the single solution you have come up with is the only solution and not the understanding that others people experiences may have led them to a different solution, like your statement that you don't understand why other guitarists use pedalboards when you are happy with a one brand multi pedal solution. While you participate in these discussions, I really don't think enough information flows in both directions for you to learn anything new.
But for the record, the thoughts I posted and the experiences I based them on ARE directly applicable to your situation, whether you want to acknowledge that or not. I am not writing from experiences in some ivory tower gig where everything is perfectly OK. My recent resume sounds more like a wireless phone commercial, "more bars in more places".
So when I say that using my mix strategy with 12 local cover bands and 20+ guitarists in the last two months has resulted in my adjusting a guitarists fader maybe 6 times, that means it can be done at the level you are talking about. And yes, I am the 1 in 10 shows for these bands to have a soundman out front but all that means is hat they have done their homework and have their arrangements finely tuned. That means I am not spending my time troubleshooting or chasing them all over the board, but instead I am able to give them a very professional polish and make the show which may be their biggest bar gig into their best shows as well.
I can do this because I have paid attention to what works and what doesn't when I have been on bigger shows, and taken those professional level techniques back to the bars. And for many of those bar shows I have K12 and Ksub with a presonus sidestage and an iPad out front and never heard the system in the room until the first song of the first set.
Back in the army we had a saying, " if you keep doing what you are doing, you will keep getting what you are getting". At some point to induce change, you have embrace and try something new, which may mean discarding your preconceptions even if you believe in those preconceptions from experience.
I guess I am ready for the summer semester to start because I definitely have my professor hat on now.
