Ace Troubleshooter (often shortened to Ace) was a pop punk band signed to Tooth & Nail Records. According to John Warne, he came up with the band's name after reading the phrase ace troubleshooter in a history book. Ace Troubleshooter came to an abrupt end in February 2005 when lead singer John Warne left to play bass for Relient K. Toby David posted the announcement of the Ace's death on the band's message board, mentioning that even though he was not an original member of the band, he felt like he was.
