Frank Iero and Evan Nestor have found a great musical camaraderie over the span of Iero's post-My Chemical Romance career, and in this edition of Gear Factor powered by Sweetwater, the two musicians come armed with their guitars to reflect on the riffs that changed their lives.

During the episode, Iero reveals that the first song he ever learned to play was a TV theme for a show he never even saw. Yet, the Peter Gunn theme by Duane Eddy is a classic with a very recognizable guitar line and the simplicity of the track appealed to Iero, who laughs, "It’s super simple. That’s all I learned, and I'm like, 'Oh, I’m a guitar player!”

Once both musicians started learning how to play, the early '90s provided major influence. Nestor pulls out one of Weezer's catchiest early tracks while Iero reflects on how beautiful the chord progression is.

Finally, the two musicians dig into Iero's own works, with the guitarist reflecting on his own work with My Chemical Romance and recalling the creation of the ear-catching riff for "Helena." Of his solo offerings, Iero calls "Medicine Square Garden" from his new album "one of my favorite songs I've ever written, while also teasing a nod to "All I Want Is Nothing" from the Stomachaches album. Nestor leans toward the Parachutes song "Dear Percocet," while Iero reveals a bit of the influence of the track.
