Frampton first heard the talk box in 1970 while sitting in on sessions for George Harrison's All Things Must Pass. While he sat next to Pete Drake in the album sessions at Abbey Road studio, he heard Pete using it with a pedal steel guitar.
Frampton acquired one as a Christmas present from Bob Heil in 1974. He then promptly locked himself away in a practice space for two weeks, and came out with some mastery of it. Due to the success of the albums Frampton and Frampton Comes Alive!, he became somewhat synonymous with the talk box.
