I'm sorry, but you really can't compare Buckethead to Hendrix, two different eras, and two different styles. As previously posted, Buckethead studies other guitarists and their styles, he then adapts them into his own music. I like to believe that Jimi Hendrix truly pioneered the amazing riffs of the electric guitar, and he truly made the electric guitar the instrument it is today. You can't say Hendrix's music doesn't have emotion, if you watch the man live you can see it in how he plays, he feels the song, he truly makes the crowd feel the amount of emotion in his playing. Hendrix is the only artist that has really emotionally hit me in such a way that I am just awe struck after the song is over.
You can just feel the power in this song.
