In 2006, the band launched their first ever major tour, The Pick of Destiny Tour. Black and Gass wished to recruit electric guitarist John Konesky and bassist John Spiker, both members of Gass's side-project Trainwreck, and had been session musicians on The Pick of Destiny album. The band also wished to recruit drummer Brooks Wackerman from The Vandals. At early rehearsals of the tour, Black and Gass contemplated whether to go ahead with the musicians, or whether to continue performing acoustic, of which they decided to try the tour with the band. The tour would continue into 2007, with two US legs, a European leg and an Australian leg.
