The 3 different tones displayed by Eric Johnson on his track Trademark are my favourites: sparkling, airy cleans; solid, slightly overdriven crunch and that searing, violin like lead tone all do it for me.
At the other end of the scale, John Frusciate’s often clanky, ‘uncaring’ tone winds me up and wonder what people see in it (he does have other, more pleasing tones of course). Of course now I can’t think of the specific example I was going to post - watch this space.
