Since 2012, Farrar is touring with Maroon 5 - as an additional band member - on guitars, occasionally on the bass guitar, percussion, backing vocals, turntables and providing samples and other special effects (using the MPC). He co-wrote and co-produced a few of the band's songs on almost all of their studio albums and also remixed one of their songs, which is called "Woman", on "", released in 2008. On August 31, 2012 - during a show in Argentina on the "Overexposed" World Tour - Farrar filled-in for Mickey Madden on the bass guitar for the very first time. He subsequently filled-in for Madden on the next few shows of the tour. In 2016, he has become an official member.
