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.

Multi-instrument compatibility is what makes this compact amp special, and this is reflected in the many positive reviews that continues to pour in. While most of the positive remarks point to its electric guitar sounds, there are a good number of users who found the acoustic voicing to be quite pleasing as well.

The need to buy an AC adapter (Amazon link) separately irked a few users who insist that it should be included in the package. Also note that the Roland Mobile Cube is now out in the market for almost a decade, so it won't have modern features. On the flip side, its longevity is a good testament to its quality and good market reception.

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.
