The Yardbirds' first recorded the song with an Indian sitar player performing the distinctive instrumental figures. However, the group were dissatisfied with the results, so Beck developed the part on electric guitar to emulate the sitar. A contemporary review described it as an "oriental touch" and music writers have identified Beck's contribution as introducing Indian-influenced guitar stylings to rock music and one of the earliest examples of what became known as raga rock. Beck's use of a fuzz box has also been cited as perhaps the first significant use of the effect.
