The Rolling Stones
Richards' sparse introduction uses open-G tuning and a thumb-and-finger attack that leaves unusually large spaces around the notes. Mick Taylor supplied the cleaner country-influenced lead fills between vocal lines, but the precise session guitars and amplifiers are not firmly documented. Settings approximated from the confirmed tuning, guitar roles and Stones' late-1960s edge-of-breakup sound. Source: Guitar World's Rolling Stones riff feature and Guitar Player's 1969 tour history.
