[Wynonie Harris]

Dick Dale's an excellent choice and Granny Claret has picked a good 'un too with Duane Eddy. However, for me it's a choice between Scotty Moore - he played on the early Elvis sides and practically invented rock guitar playing - and Link Wray - his "Rumble" is one of the most influential instrumentals ever - Townshend, Clapton, Page and many more all cite it as a major influence.
