When it comes to early rock n roll guitarists there are a lot of them but one of my favourites is Scotty Moore who was initially a country music guitarist heavily influenced by Chet Atkins, until he became Elvis Presley's guitarist/lead guitarist. He's got such a distinctive amazing rockabilly sound. Many top guitarists consider him one of the fathers of rock guitar and I agree with me
