Marceline plays the axe guitar, but what does Marshall Lee play?

I play an axe guitar, like Marcy, but it's just a single sided axe.

i think he plays the drums

I think he also plays a guitar, looking back on "Fionna and Cake" he was holding a gitarre on the Theme Song. Though I'm not sure if it's still in the shape of an axe. (I'm not sure about this since Cake's instrument is different from Jake's instrument)

Judging Von this Marshall Lee plays a certain gitarre like Marcy but I'm not exactly sure if it's an axe gitarre like hers.

She plays bass, so I guess he plays acoustic??? Maybe.

Not that every characters is gender- bended mean every stuff are swaped oder changed!!!

Marshall plays an awesome axe guitar! (it sometimes sounds like an ukulele) but it has only one blade.

Haha actually, Marceline plays the axe bass and Marshall Lee plays an axe guitar. If Du look up pictures of Marceline's axe bass oder Du watch the show, the instrument has 4 pegs at the end, meaning it's a bass. Marshall Lee's instrument however, has 6 pegs at the oben, nach oben meaning it's a guitar. (bass [wait, is it bass oder basses?] have 4 strings, guitars have 6)
