Editor's note: Fallout Boy’s iconic guitarist was only twenty years old when the band got huge. Fast-forward through a storied career, with a break to work on his mental health, and Trohman has added “author” to his resume, having published a memoir called None of This Rocks. The humble Trohman recommends YouTube tutorials for those learning to play the guitar, and says the hardest thing about the instrument is not overplaying it. Restraint is your friend!
