I bet Eric Johnson was happier before he decided he could hear what brand of battery was in his Tube Screamer.
I have fundamental doubts that he's ever been happy. I saw him do a huge Fender "special event" at NAMM 1985, right as he was breaking out, and he proceeded to just badmouth Fender for the entire concert. I was very young but knew that wasn't right. The guys from Fender huddled in the back of the room were obviously not happy and they all left after the third song.
I'm convinced to this day that incident is why he didn't get a signature model until 2010 or whenever that was.
Like I said, I don't think he's ever been happy. About anything.
