The best visual book I can think of is Lynda Barry's What It Is, but although I refer to it all the time it's not a creative writing book per se.
There are lots of really good guitarists, but they play with the same pedals that everybody else does. Everybody buys the same pedals, so the sounds tend to be the same. I am looking for different ways of doing that without having to spend days and weeks and months fooling around with pedals, which I don't enjoy.
