During his career Jimi used many effects both in the studio and in live performance. For example, Jimi used many fuzz box units among which were the Arbiter Fuzz Face, the 'Axis' fuzz , and the Mosrite Fuzzrite. Another effect that Jimi used and has since become synonomous with his name was the Vox wah-wah pedal. Jimi employed this effect on many of his studio recordings such as "Voodoo Chile (slight return)," and "Burning of the Midnight Lamp." A third type of effect that Jimi used in the studio was a Leslie Speaker cabinet. This effect created the swirling sounds heard on studio tracks such as "Little Wing" and "House Burning Down."
A fourth effect Jimi used was the Octava. This device, as noted by "Jimi Hendrix: Electric Gypsy," "gives the effect of a multiple mirror image of the actual sound," but phased inverted. So really it produces a sound that absolutely multiplies all the harmonics up, almost to infinity, so you get an extremely high tone out of it." The Octavia made it first appearance on "Purple Haze."
Finally, there is undoubtedly a plethora of other effects that Jimi used in the studio other than just the ones that were mentioned above but to name and detail all of them would take far too much time. The only thing left to be said is that Jimi Hendrix was enormously gifted and was one of the most brilliant musicians that has ever lived.
