Of Presley's first single "That's All Right", the critic Dave Marsh wrote that "Moore's guitar—especially the solo—toughens the song up and forces it to rock." Though Marsh credits Presley with introducing "the vocal stutter" on "Baby Let's Play House", "Other than that, it's guitarist Scotty Moore's show and he sets a few precedents of his own." Of the other Sun recordings, Marsh cited the "urgent Scotty Moore guitar lick" as a standout element of "Mystery Train", while "Good Rockin' Tonight" displays his "stinging guitar". Scotty added a touch of reverb to his guitar. And it ended up being a very good call.
