Shiflett was born in Santa Barbara, California. When Shiflett was 11, he started learning how to play the guitar. A promising young soccer player, Shiflett played AYSO under legendary SB coach Noemi Vazquez from 1982–84. Pressed to make a choice on his career, Shiflett joined his first band by the time he reached the age of 14.\n', '
Shiflett was the resident lead guitarist for the San Francisco Bay Area punk rock band No Use for a Name. When a friend announced that Guns N\' Roses were auditioning for a guitarist, Shiflett asked his friend to instead get him an audition for the Foo Fighters, who after recording There Is Nothing Left to Lose as a trio held open auditions to hire another guitarist. Dave Grohl said part of his motivation to hire Shiflett was that he had a history in the underground punk scene, including opening for Grohl\'s former band Scream as bassist of the group Rat Pack. After being hired, Shiflett played on the tour for There Is Nothing Left to Lose, and all subsequent studio albums starting with One by One. Shiflett has noted several times that one of his favorite songs that he plays with the Foo Fighters is "All My Life" from their fourth studio album One by One. Shiflett has declared that he was afraid of being fired even before he started to play with the band, as previous guitarist Pat Smear had declared interest to rejoin (Smear eventually got back with the band as a touring rhythm guitarist in 2005, rejoining as a full-fledged fifth member in 2010).\n', '
Seeing an opportunity that he knew he could not pass up, he quickly parted ways with his former band to audition. His departure was abrupt, as No Use for a Name were just about to head out on tour in support of their then-recent album More Betterness!. He was replaced by Dave Nassie, who had previously contributed to Suicidal Tendencies\' lead singer "Cyco" Mike Muir\'s solo projects.\n', 'Shiflett began his music career in another band called Lost Kittenz with current members of Sugarcult. He also currently plays in the punk rock cover band Me First and the Gimme Gimmes, his own side-project, Jackson United as well as Viva Death with his brother Scott. For numerous projects, Shiflett performed under the name Jake Jackson. He is also a sometime member of cover band Chevy Metal with Foo Fighter Taylor Hawkins. They play songs from classic rock bands such as Black Sabbath, Queen, ZZ Top, and Rolling Stones.\n', '
