The guitar is seen again while Greg plays "Wailing Stone".
Greg plays the guitar at the beginning of the episode, transitioning to young Greg performing "Comet" in the flashback. A similar guitar can also be seen with young Greg in the past.
Greg offers guitar lessons and has Steven hand out flyers. At the Car Wash, he sits with his guitar ready to teach any newcomers. It also is represented in Steven's poster.
Greg uses the guitar to play "Don't Cost Nothin'".
Additionally, Greg also owns a "Jader" model electric guitar, prominently used earlier in his musical career. Songs including "Comet" and "What Can I Do" have been performed with this particular instrument.
- When Steven's poster has lightning bolts coming out of the guitar (for effect), Garnet suggested rocks to be flying out of it as Steven has said that the guitar "rocked".
