Marceline adventure times guitar?

I'm not sure if there's a store that sells the exact guitar, but you have to make it by yourself.

For the tuner head bolty things use: brass tacks

For the tuner bolts use: model magic and wooden screws

For the bass strings use: grey yarn

For the frets use: wooden dowel

For the pick ups use: acrylic paint

For the knobs use: water bottle caps

For the bridge use: jenga piece

For the pointy end thingy use: model magic

I don't thing that is a real guitar, because there might never be a real one.
