Gus G.

Kostas Karamitroudis aka Gus G., born September 12 1980 in Thessaloniki, Greece is an acclaimed heavy metal guitarist currently with Firewind and Ozzy Osbourne. He has also played in Mystic Prophecy, Nightrage, Arch Enemy and Dream Evil. At the age of 18 he left Greece to enroll in the Berklee College of Music, but left after only a few weeks and began working on making a name on the Metal scene. During his brief time at Berklee Gus came into contact with Joe Stump, who he credits as a great influence on his career.

On July 2005, he temporarily replaced Christopher Amott as guitarist of melodic death metal band Arch Enemy on their Ozzfest dates, and also contributed to their album Doomsday Machine by playing lead guitar on the song "Taking Back my Soul".
