Just came across a Gibson online article that is similar to two of my early postings, the July 2, 2012 On Using Your Ears, and the July 19, 2012 More On Using Your Ears. In the Gibson article, Dave Hunter talks about "home tone" vs. "gig tone." The take-away line for me is
"When you get “your tone” set up and ready to go in sound check, then
find it is lost in the ether once the band kicks in, don’t be too
proud—or too stubborn—to change it."
And he sums it up with
"...get your tone out there to the ears that matter most to the live performance: someone else’s."
It's a good read for another take on this topic.
