Marceline's amps

Marceline's main amplifier makes it's debut in "It Came From The Nightosphere." It can be seen in the background as Marceline plays the Fry Song. It makes another appearance in "Go With Me" when Marceline is about to practice her Axe Bass, but is interrupted by Finn. The control panel features four dials, the one to the far right being for volume, with the other three possibly being tone controls for bass, midrange and treble. It also has a power switch and a headphone jack. Marceline's name is also inscribed in purple cursive letters beneath the control panel.
