Card Trivia:Tuning
- "Spirit of the Harp" appears in this card's artwork.
- "Junk Synchron" appears in this card's second artwork.
- This card's name and first artwork are a pun, as "Spirit of the Harp" is "tuning" a harp, yet "tuning" is a term used for sending Synchro Material Monsters to the Graveyard for a Synchro Summon.
- This card's second artwork depicts "Junk Synchron" undergoing the process of "tuning" by activating the engine on its back, which is commonly depicted in the Yu-Gi-Oh! 5D's anime.
- "Junk Synchron" appears in this card's second artwork.
- This card has a parodied counterpart: "Hell Tuning".
- This card has a "Speed Spell" counterpart: "Speed Spell - Tuning".
- This is one of several cards that got both nerfed and improved at the same time. This card was nerfed because in the anime it can add any Tuner, while in the OCG/TCG print it can add only "Synchron" Tuner monsters, but this card is also improved because in the anime the player needs to send cards with an amount equal to the added Tuner's Level, while the OCG/TCG print only require them to send the top card of the Deck.
- This card's Tag Force 4 effect is a combined version of the anime effect and the OCG/TCG effect - in Tag Force 4, this card lets the player add only "Synchron" Tuner monsters just like in the OCG/TCG print, but also requires them to send cards with an amount equal to the Tuner's Level, just like the anime effect.
