Biographer David Henderson describes Hendrix's guitar tone as "at the razor edge of distort". However, individual notes are still clear, as well as the harmonically more complex chords, even with the use of extreme overdrive for the time. The tension is maintained until the guitar solo, which "arrives as something of a release rather than a further racking up of the atmosphere." It is also when Hendrix first introduces the Octavia, coupled with a Fuzz Face distortion unit. Whitehill describes the solo as "almost sound likes he's playing a blues raga. He starts out playing in the Mixolydian mode and then he goes right into the blues side. The Octavia has the effect of a sitar, kind of like Ravi Shankar meets B.B. King." During the song's outro, the guitar part recorded at 7½ inches per second (ips) played back at 15 ips, is combined with the Octavia, further extending the guitar's upper frequency range. Henderson describes it as "an uncanny piercing tone that takes off, Eastern-sounding beyond the range of the guitar" and, according to Shadwick, "gives the impression that the guitar notes are flying off into the ether."
