Meet the new MICRO CUBEs — small, loud, proud, and in true stereo! These little amps overachieve with serious bombast in a small body. You won’t believe how much these little amps can deliver through their stereo power amps and newly developed custom speakers, four per RX.

  • Stereo power amplifiers and four newly developed 4-inch (10cm) speakers
  • Eight COSM amps, six digital effects,
  • Rhythm Guide function for practical rhythm training

New Speaker Tech
Consider them the ultimate compact amps with high-quality, powerful sound. The cutting-edge speakers used in the MICRO CUBE BASS RX are custom designed and built specially for these amps.

Stereo Power Amps
With two specially made power amps and four speakers contained in each, the RX amp produces an immersive, stereo sound that must be heard to be believed. The true stereo engine also allows bass tones that defy the size of the cabinet.

Battery Drive
The MICRO CUBE BASS RX can run on battery or AC power (AC adaptor included). But did you know that the MICRO CUBE BASS RX is a pioneer on the battery-operated bass amplifier market? At last, bass players have a rockin’ battery-operated amp solution!

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 BASS RX benefit 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 BASS RX’s onboard stereo effects benefit from Roland’s decades of industry-leading R&D. Experience the amazing spatial depthand lush sound of the stereo Chorus and Reverb.

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 BASS 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.

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 BASS RX.

The MICRO CUBE BASS RX’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.

Best practice amp!





Tone max practice amp


I am very happy with this practice amp. Newer bassists will want something with more punch to jam with in the garage. Those of us that either have a separate gigging amp or a simple need for portability and in-home use will find that this is a great buy. The tone is great and the rhythms are essential for practice. Great for amplification around the fire pit. Back when I toured I would have loved this on the bus. Not for starving musicians. My Ken Smith sounds true. See you in the pocket!



Good amps for the size and price!!!


Excellent amp, versatile!



I would not hesitate to buy again


Bought to play the acoustic bass with an " Old Time Music "group and it is everything I wanted. It is used primarily outdoors for the group and indoor practice with my wife on the fiddle.

Great little amp.


This amp is a real asset for jams in areas with no power outlets. I have used it with my upright, Eminence EUB, & Martin acoustic basses for big band practice, outdoor acoustic jam sessions. Great little amp!

Best Choice for Portable Bass Amps


There are not many choices for battery-powered bass amps, and virtually none that don't have a heavy rechargeable battery to add weight. The Roland seems the best of the lot. I needed an amp that can ride in a bike basket with my UBass over my shoulder. Really don' t need the models and effects. At other times, I have used a Roland Street EX for bass, which also works fairly well.
