Do you consider Chuck Berry a great guitar player

So now, the hallmark of a great guitarist is whether they can write a rock 'n roll song?

I don’t know whether to believe you or these guys:

By far the most astonishing guitar player ever has got to be Django Reinhardt … Django was quite superhuman, There’s nothing normal about him as a person or a player. — Jeff Beck

“He was the greatest guitarist in my mind. I’d do anything to play as great as he did.” Les Paul on Django Reinhardt

“Even today, nobody has really come to the state that he was playing at. As good as players are, they haven’t gotten to where he is. There’s a lot of guys that play fast and a lot of guys that play clean, and the guitar has come a long way as far as speed and clarity go, but nobody plays with the whole fullness of expression that Django has.” - Jerry Garcia
