seen using it for the song on BBC television program "Five Faces of the Guitar" in 1974 in which he also explains its use to the host of the show. Heil high-powered talk box The first high-powered talk box was developed by Bob Heil. Heil came up with the first high-powered talk box that could be reliable when used on high-level rock stages. His first Heil talk box was built for Joe Walsh's Barnstorm tour. Heil and Walsh, both avid ham radio operators (K9EID and WB6ACU, respectively), along with Walsh's guitar tech "Krinkle", combined a 250-watt JBL driver and suitable hi-pass filter which was used for Walsh's single "Rocky Mountain Way". Walsh gives credit to Bill West, an electrical engineer, Nashville steel guitarist and first husband of country-music legend Dottie West, for inventing the talk box for him in a 2006 interview with Howard Stern. Pete Townshend, in his 2012 autobiography Who I Am, claimed to have invented a version of the talk box during a Who tour of the US in 1976. "I built a speaker in a small box, attached a tube and put the tube in my mouth, allowing me to speak music." In 1988, Heil sold the manufacturing rights to Dunlop Manufacturing, Inc., which currently builds the Heil talk box to the exact standards that Heil designed in 1973. The classic rock artist Peter Frampton made extensive use of the talk box in his music. In an interview for the 1999 DVD Live in Detroit, Frampton says he 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 Studios, he heard Pete using it with a pedal steel guitar. Frampton said in the same interview that the sound it produced reminded him of an audio effect he loved listening to on Radio Luxembourg in the later 1960s. Frampton acquired one as a Christmas present from Bob Heil in 1974. It was a hand-built talk box in a fiberglass box using a 100-watt high-powered driver. This was the Heil talk box used for the Frampton Comes Alive tour and album. 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!, and
