Good 'ol boy Tom. He put this up as part of his "double lip embouchure" series, but this video is chock full of common sense. He obviously uses a much softer setup than most saxophonists, but he can play a double high C without moving his embouchure at all.
This video also demonstrates Ridenour's ATG reed finishing system, but the principles here will work with just plain sandpaper, or a knife, or a geek-thingy, or ...
The main point to pay attention to is BALANCING YOUR REED BEFORE DOING ANYTHING ELSE!
