The Mobile Cube appeared on our recommended list for Keyboard Amps from October 2020 until September 2022 when it was out-ranked by the Peavey KB 2 and Roland KC-80.

Although this was previously on our recommended list, there are now amps with higher ratings in our guide to The Best Keyboard Amps and The Best Battery Powered Guitar Amps.

The Roland Mobile Cube is the amp of choice for multi-instrumentalists, with inputs and features that are specially dedicated for mic, guitar and even keyboard.

These features include dedicated acoustic amp voicing, clean, overdrive and distortion settings for electric guitar, and two voicings for keyboards – fat and normal.

It also comes with built-in stereo effects that include Chorus, Delay and Reverb.

With its 5W amp configuration and dual 4″ speakers, this mobile cube is not meant to be loud, but it has enough power for practice both indoor and outdoor.

If you are a multi-instrumentalist, or if you’re looking for an amp that handles keyboards and mic, then check out the Roland Mobile Cube.
