A little amp that's bigger than its britches.
Meet the Roland Micro Cube guitar amp -- small, loud, proud, and in true stereo. This little amplifier overachieves with serious bombast in a small body with a stereo power amp and four redesigned custom speakers.
Speaker Tech
The cutting-edge speakers used in the Micro Cube RX are custom designed and built specially for Micro Cube amps.
Stereo Power Amps
With two specially made power amps and four speakers contained in each, the RX amp produces an immersive, stereo sound. The true stereo engine also allows bass tones that defy the size of the cabinet.
Battery Drive
The Roland Micro Cube Rx amp can run on battery or AC power (AC adaptor included).
COSM Amps & Digital Effects
Guitarists and bassists have come to rely on Roland and BOSS for the best effects in the world. The Micro Cube Rx amplifier benefits from this world-leading technology, offering eight built-in COSM amps, six digital effects, three band EQ, and a chromatic tuner.
Immersive Stereo FX
The Micro Cube Rxs' onboard stereo effects benefit from Roland's decades of industry-leading R&D. Experience the amazing spatial depth and lush sound of the stereo Chorus and Reverb.
Like Roland's popular Jazz Chorus amps, the Micro Cube RXs' chorus effect takes advantage of the dual-speaker configuration to deliver the widest and most spacious chorus possible.
Rhythm Guide
The metronome is a music-student's best friend, but that numbing "clank, clank, clank" can get irksome. That's where the Micro Cube Rx's Rhythm Guide comes in handy. It's like having a drummer inside your amp. Choose from an assortment of groovin' patterns to practice with. Improve your timing while having a more enjoyable musical experience, or just have fun jamming along to the beats.
Outputs
The Phones/Recording output serves two purposes: Plug in a set of headphones and enjoy private practice with lush, stereo sound, or plug directly into a stereo mixer or recording device for accurate signal transfer directly from the Micro Cube Rx.
Inputs
The Roland Micro Cube Rx amp's line input lets you plug in a guitar, bass, or microphone. In addition, the stereo AUX input accepts input from an iPod, a CD player, or musical instrument so you can blend its signal with your own.
