Agree on your comment about The Edge. He is quite musical in his use of effects and gets extra points in my book for his use of them live.
Can't agree on the Keith Richards comment. He combined a unique blend of American roots Blues rhythms and open tuning effects into Rock. It changed the sound of Rock in the mid-late 60's and onward. However, if you are talking about the Keith Richards of today....I would agree that he has been in cruise mode since the late 80's. But he is 70 and that shouldn't negate his earlier amazing contributions.
