I am not sure I can pick any one artist. I fell in love with the sound of an electric guitar through a driven amp. There are many examples of this and many different tones that hooked me in. Some that come to mind from my early years were Alex Lifeson, SRV, George Lynch, Eddie Van Halen and probably many more I am not thinking of at the moment.
I remember hearing some of that really early Rush and loving what I was hearing. A neighbor that was a little older than me was playing it a lot in his garage and car. I asked him who it was so I could get my hands on some of that music.
I was really hooked on a lot of the tones in the hair metal days. That was a few years after discovering Rush. Then I heard SRV when he hit the scene. Man, I loved the sound of his Strat. I think these guys and bands are the reason that I really have an appreciation for single coil tones as well as humbucker tones. I love the sounds that Brent Mason gets too. I can't play like that and have never really tried to learn to. I am not sure why. I really like the sound of it. I have even gone through acoustic phases and have a great appreciation for that type of music as well.
EDIT.
I knew I would forget at least one important influence, Billy Gibbons. I am sure he is not the only one I forgot.
