 For much of "Stadium Arcadium", guitarist John Frusciante experiments with a vast array of synthesized effects, many of which are reminiscent of the idiosyncratic timbres found on 2004’s "Shadows Collide With People".The ghostly outro of “Slow Cheetah” is a clear example of Frusciante’s affinity for psychedelia, and provides a stark contrast to the song’s acoustic beginning.The backwards guitar at the song’s outro is similar to 1991’s “Give It Away”, where Frusciante used the same technique.
