Rainbow Dash visits a music shop with her friends to replace her broken electric guitar with one that "looks as awesome as [she's] gonna make it sound." A double-necked guitar catches her eye, but Trixie grabs it at the same time she does, and the two begin to fight over it. At Applejack's suggestion, Rainbow Dash challenges Trixie to a "shred-off" to determine who will keep the guitar.
The two girls fight to outperform each other with their solo guitar riffs. As Trixie begins to gain the upper hand, Rainbow Dash's entire body levitates into the air and surges with an electrical aura, transforming her into her pony-like form and changing her guitar's appearance. Rainbow Dash hits the ground and creates a sonic rainboom-like shockwave that blows Trixie aside.
The other girls applaud Rainbow Dash's performance, but as DJ Pon-3 hands her the double-necked guitar, Rainbow Dash decides to let Trixie have it, saying her transformed guitar is the one that "really speaks to [her]." Trixie gloats over her self-supposed victory as Rainbow Dash leaves with her new guitar, only to read its price tag and realize her prize costs $12,000, and swears revenge on Rainbow Dash.
