Overview

The Roland MOBILE CUBE is a battery-powered stereo amplifier built for musicians and audio enthusiasts who need sound reinforcement without being tethered to a power outlet. It delivers 2.5 watts per channel through stereo speakers and accepts a wide range of inputs — electric guitar, acoustic-electric guitar, keyboards, MP3 players, and computer audio — making it one of the most versatile portable amps available. Built-in effects including overdrive, chorus, delay, and reverb let guitarists shape their tone without hauling extra pedals, while the Center Cancel feature removes vocals from recorded tracks for karaoke-style sing-alongs.

Powered by six AA batteries, the MOBILE CUBE is compact enough to slip into a briefcase, making it ideal for busking, small jam sessions, park performances, and travel practice. Its stereo output provides a wider soundstage than typical mono practice amps, and the straightforward controls make it easy to plug in and start playing immediately. Whether you need a quick practice amp at home or a portable sound solution for impromptu performances, the MOBILE CUBE covers a surprising range of use cases in a remarkably small package.
