Information:
The original lineup of the Sex Machineguns at their debut, consisted of Anchang (vocals, guitar), Sussy (guitar), Noisy (bass), and Speed Star Sypan Joe (drums). Joe had to leave the group in 1999 due to lower back pains, and they replaced him with drummer Clutch.J.Himawari. In 2001, guitarist Sussy left the band, and was replaced by Circuit.V.Panther.

In 2003, the group disbanded with this lineup. Anchang would have a brief solo career under the name "Sex Machinegun", and the group would reform in 2004 with a slightly modified lineup. Replacing bassist Noisy with Samurai W. Kenjilaw (formerly of Cali Gari), and bringing back original drummer Speed Star Sypan Joe.

In 2006, breakup would strike the group again. All of the current members (except for Anchang) would leave to form a group called Elleguns, and Anchang would return to his solo career (this time going by the name "Anchang", not "Sex Machinegun"). In 2007 Anchang would once again reform Sex Machineguns, but with a brand new lineup (as can be seen above), using support member Shingo* as a bassist.
