 Entwistle eventually switched to using a Sound City rig, with Townshend following suit later as well.Townshend points out that Jimi Hendrix, their new label mate, was influenced beyond just the band's volume.Both Entwistle and Townshend had begun experimenting with feedback from the amplifiers in the mid-1960s, and Hendrix did not begin destroying his instruments until after he had witnessed the Who's "auto-destructive art".
