Eddie Munson had a very memorable scene featuring his guitar in Stranger Things season 4, but the details from the sequence prest a plot hole.
Warning: Spoiler for Stranger Things season 4, volume 2!
Eddie Munson made a heroic sacrifice in the Stranger Things season 4 finale, but his fate in the Upside Down presented a glaring plot hole. Joseph Quinn served as a newcomer in the latest installment of the Netflix series, but he instantly became a fan favorite. Despite his hardcore intimidating rocker aesthetic, Eddie was one of the kindest souls to grace the town of Hawkins. Sadly, Eddie died in Stranger Things season 4, but not before putting on a show with his electric guitar.
After being accused of murdering Chrissy, Eddie went on the run out of fear for his life. Dustin and Max led the charge in finding Eddie, who they knew was innocent, as more of their allies joined in protecting him. As time went on, the mystery surrounding more deaths in town grew deeper, with Vecna emerging as the new main antagonist. Eddie saw first-hand what terrors plagued the Upside Down after assisting in Steve's rescue from the Demobats. He also stuck around to help the Hawkins group carry out a multi-phase plan to kill Vecna while using Max as bait.

Eddie and his fellow Dungeons & Dragons buddy Dustin were in charge of phase 3 of the group's plan in Stranger Things season 4's "The Piggyback." Once Max caught the attention of Vecna, Dustin and Eddie remained near Eddie's trailer in the Upside Down to distract the horde of Demobats. To do so, Eddie grabbed his beloved guitar and played Metallica's "Master of Puppets" on the trailer's rooftop, a move that instantly grabbed the creatures' attention. The Stranger Things sequence showed that the guitar was connected to amps powered by extension cords. However, this brought up a plot hole because there hasn't been electricity readily available in the Upside Down, so powering the amp in the alternate dimension doesn't make sense.
Before Eddie began fervently playing "Master of Puppets" on his electric guitar, Dustin was seen connecting a long extension power cord to the amp on the roof. Granted, the extension cord would have needed to be connected to a power source, but one was never shown. It could be assumed that the cord connected to power within the trailer, but again, there hasn't been reliant electricity in the Upside Down. Aside from a few surging street lights, the prevalent electricity seen had stemmed from signage, like the arcade sign in season 2 and the Starcourt Mall in season 3. But even this infrastructure in focus was always connected to the Mind Flayer's whereabouts, suggesting it charged up the areas similar to how humans can manipulate certain forms of energy within the Upside Down.
As for normal forms of energy in the Upside Down, Eddie, Steve, Nancy, and Robin witnessed a fallen tower of power lines earlier in the season. They also attempted to turn on lights in the alternate version of the Wheeler house to find that complete darkness was the only option, suggesting it was the same case across all households. Perhaps the extension power cord reached through the Gate in the trailer's ceiling along with the rope used to travel through the portal. That would allow the electricity to originate in the normal dimension, flow through the Gate, and power the amps for Eddie's guitar. Unfortunately, when the rope and Gate were seen throughout the rest of the episode leading up to Eddie's death, no such power sources existed on-screen, resulting in the plot hole. Stranger Things has proven that the Upside Down can affect electricity in the normal dimension through magnetization. However, the rules and consistency surrounding how electricity works within the dimension remain unclear.
