The next day, Rainbow Dash has invited the girls to come with her to the music story. She explains to them that she needs a new guitar for the band, but some of them are not sure why. As they walk into the story they can see Vinyl Scratch, one of their classmates in the store. They remember, she works here.
Then Rarity asks, "Rainbow Dash, I simply don't understand why you can't just play the guitar you have."
Rainbow Dash opens the guitar case to show them the guitar she originally has. The guitar is dirty and broken, some of the coloring is rubbing off, rusted, and one of the strings just broke.
Rarity gasps with a shock and calmly says,"Now I understand."
"It's old, and it's a wreck," Sun replies.
"That's why I need to get a new one," Rainbow Dash says.
Pinkie holds out a pink electric guitar and happily asks, "How about this one?!"
"No," Rainbow answers.
"Lookie here!" Pinkie says, holding a banjo.
"No," Rainbow answers.
"Super cool," Pinkie adds, holding a trumpet.
"No Pinkie," Rainbow answers while shaking her head.
"Well, what you're looking for?" Applejack asks.
"That's the problem. I need something that looks as awesome as I'm gonna make it sound," Rainbow Dash explains, as she looks around.
She gasps in amazement seeing something amazing. It's an electric guitar, red with lighting, yellow stars on it, and have two stems and two sets of guitar strings. It's not only big, but it's so awesome. Rainbow Dash has the I gotta have it look in her eyes.
As she grabs one side of the guitar, someone else grabs the other side. Rainbow looks to see that Trixie is holding the other one. Meaning that she wants it too. It' turns into a tug a war for the guitar.
Rainbow pulls to her and angrily says, "Hands off my guitar, Trixie!"
"I touched it first, Rainbow Dash!" Trixie firmly says pulling it to herself.
Sun get's between the feuding girls and calmly says, "Girls, I'm sure there is a better solution than fighting over it."
"Sounds to me like this is making for a nice, friendly competition," Applejack adds with a grin in her hace.
"Alright! Let's see who plays best?!" Rainbow says with pride.
"A shred off." Trixie says, narrowing her eyes.
"Shred on!" Rainbow says competitively, and narrowing her eyes.
With that, Pinkie gives Rainbow Dash a blue guitar and start to strum on it in a rock music tone. Trixie has a orange guitar and is strumming on it as well. The two are not about to give up, so they play the guitar even louder, and stronger. Trixie is playing the guitar louder than Rainbow Dash. Rainbow is about to be defeated, but she is not going to give up without a fight.
Just as she strum a few tones on the guitar. Rainbow eyes start to glow, and her guitar turns bright blue, with a red stem, and yellow lightning then starts to levitate in the air as she plays. Trixie and the girls become shocked to see Rainbow is floating in the air. As it more surprising, Rainbow grows pony ears, wings on her back, and an extended pony tail.
As Rainbow plays the final melody on the guitar, she slams into the ground and creates a sonic rainbow along with a strong boom. Trixie's has been blown away from the final play, literally. When Rainbow Dash finishes playing the music, Sun and the others cheer for her in amazement for her performance. Trixie pushes the drum out of the way to see the transformation, and gets up to clean herself.
"Check me out!" Rainbow says, astonished by the pony up, and wings.
Vinyl walks up to Rainbow Dash so she can claim her prize, but something stops her. She looks at the guitar she uses for the shred off and see how amazing it it. She realizes that she ended up making the guitar more awesome that the one she wants to win for. With that she make up her mind on what guitar she wants to buy.
"She can have it. Turns out this is the one that really speaks to me," Rainbow Dash says as she hugs her new awesome guitar.
Trixie grins after hearing that, and announces, "The Great and Powerful Trixie always wins in the end!"
After taking it from Vinyl, and raising it in the air, She laughs maniacally with pride. She really glad to have get the guitar.
However, Rainbow Dash and the girls walk past Trixie and are going to leave the store.
Rainbow Dash says as she walk by, "I doubt it."
Rainbow comes up to Vinyl who is now at the register, pays for the guitar, and leaves the store with her friends. Vinyl then turns to Trixie to see if she's ready to pay. Trixie's looks at the guitar and is glad she won, but decides to see the price. When she faces the guitar's back side, she can see the price tag reading, '12,000' on it.
"Twelve Thousand Dollars!" Trixie shockley exclaims.
She becomes furious and announces, "You'll pay for this, Rainbow Dash!"
"No silly. If you want, you'll have to pay for it," Pinkie says by the door, and leaves with the others.
Trixie's doesn't seem to like it, and angrily shouts, "That is so not funny, Pinkie Pie!"
"It is to us," Rainbow says to the others with a smug on her face.
The girls start to laugh hearing the comment. Rainbow is glad that she has her new and yet, special guitar now. As they leave the store, Sun starts to wonder about the transformation Rainbow displayed. She is starting to think that, something inside of her caused her to changed as she plays music. Sun decides to wait until something else happens before she can send a message to Twilight and Princess Celestia with the journal. Until then. She needs to see what happens next.
