Marceline's instruments

Marceline's basses refer to three bass guitars that Marceline has been shown to play in Adventure Time.

Rickenbacker 4003
Marceline's original bass is introduced to Adventure Time in "Evicted!"; she carries it around with her while frightening Finn and Jake. The guitar is a red, four-string Rickenbacker 4003 with a thumb rest and two dials, one each for volume and tone. She carries the Rickenbacker around with her for much of the episode. This bass, however, has not appeared in any episode since, as Marceline prefers to play the Axe-Bass. The Rickenbacker 4003 is the first of three bass guitars Marceline has introduced to the show.

Axe-Bass


The Axe-Bass is Marceline's family heirloom and by far her favorite bass guitar, receiving more on-screen time than her other two basses combined. It first appears in "Henchman," which Marceline uses to play the "Fisherman Song." The Axe-Bass is a double-sided, battle-axe converted into a fretless, four-string bass guitar by the addition of two machine heads on either side, a headstock, pickups, and volume and tone dials. The Axe-Bass is the second, and most lasting, of three bass guitars Marceline has introduced to the show.

Butterfly Bass
The Butterfly Bass makes its debut in "Heat Signature," when Finn and Jake visit Marceline to show her a movie by the same name. The bass is a dark-pink, four-string with a blue headstock, the body of which is stylistically reminicent of a butterfly. Due to its unique construction, it may be a neck-through model. It doesn't appear to have any volume or tone controls, although there is a dark circle on each wing. It also seems to have two spikes flaring off the upper wing.
