Watch the Keith Richards online guitar lesson by Jeff McErlain from Kings of Tone
Keith Richards set up is pretty old school and simple, guitar - chord - amp. That's it. Simple, cool, and all right at your fingertips. It's a classic setup that works and whenever possible is the way I like to play best. His tone is fairly clean as distorted tones go, it's punchy and articulate which is important for his style of playing because if you can hear the chords he is playing clearly. Often heavily distorted tones can cloud more complex chord voicings, for classic rhythm sounds usually the cleaner the better!
