as the best performance, a reduction mix was carried out on 13 April, freeing up space for more overdubs on the four-track tape. Harrison added another vocal part onto what was now referred to as take 7, and Ringo Starr played tambourine. McCartney contributed a high harmony vocal over the words "They'll fill you in with all their sins, you'll see", but this part was omitted from the final mix. Harrison also overdubbed fuzz-tone electric guitar, controlling the output via a volume pedal. Producer Tony Visconti has marvelled at the guitar sounds the Beatles introduced on Revolver, particularly Harrison's part on "Love You To", which he says "sounds like a chainsaw cutting down a tree in Vermont". Credit for the main sitar part on "Love You To" has traditionally been the subject of debate among commentators. While MacDonald says that, rather than Harrison, it was the sitarist from the AMC who played this part, Rodriguez writes that "others point to [Harrison's] single-minded diligence in mastering the instrument, as well as his study through private lessons, proximity to accomplished musicians, and close listening to pertinent records." In his official history of the Beatles' recording career, The Complete Beatles Recording Sessions, Lewisohn states: "George played the sitar but an outside musician, Anil Bhagwat, was recruited to play the tabla." Musicologist Walter Everett also identifies Harrison as the main sitar player on the recording, as does Peter Lavezzoli, author of The Dawn of Indian Music in the West. Leng comments that, as on "Norwegian Wood", Harrison "is still playing the sitar like a guitar player [on the recording], using blues and rock 'n' roll bends rather than the intensely intricate Indian equivalents". Speaking to author Steve Turner, Bhagwat has dismissed the idea that the sitarist was not Harrison, saying: "I can tell you here and now – 100 percent it was George on sitar throughout." Final mixing for the song took place on 21 June as the Beatles rushed to complete Revolver before beginning the first leg of their 1966 world tour. Harrison discussed "Love You To" with Shankar when the two musicians met that month, at a social event hosted by the Angadi family. Although he was unaware of the band's popularity and had yet to hear "Norwegian Wood", Shankar was impressed with Harrison's humility as the guitarist downplayed his sitar recordings with the Beatles as merely "experiments". Soon after this meeting,
