Small Size, Big Sound

The Roland MOBILE CUBE continues the hugely successful line of portable Cube amplifiers, this time with a small and mighty dual-speaker stereo amp that can double as a portable micro PA. The MOBILE CUBE will accept mics, keyboards, acoustic and electric guitars, MP3 players, and more. Built-in stereo effects let you add pro touches such as reverb and chorus. A center canceler enables you to remove much of a pre-existing vocal track for karaoke or practice. The MOBILE CUBE can also be mounted on a mic stand.

Traveler Companion

The Roland Cube amp for me. I like to use outdoors with my Traveler Guitar purchased at Sweetwater of course. Thanks for having such a large selection of musical instruments and accessories , great job Sweetwater!

Roland Mobile Cube

Sweetwater was the best deal I could find that would ship to me in Canada. Great customer service and superfast deivery means I will be this roland amp.... I love this mini amp. I have been searching for a small STEREO amp to run my microkorg and krog microstation and be totaly mobile. This amp delivers the goods. Portable, battery operated, multi lines in and out and all in stereo. I can run in any type of aux ( like the korg monotron or mp3 player or another keyboard...hold on!...even my tablet and run my music making software)...microphone in...keyboard , guitar and all at the same time. It has some weight to it and that explaines the quality of the 4 inch speakers in this sweetie. Hit the corus and run your keyboard FAT to expand the sound. Use the onboard effects. Total fun, form and function.

OVERACHIEVER! Sounds great, works terrific

I acquired a Roland Mobile Cube a couple of weeks ago, as a gift for my son. He wanted a boom box to listen to CDs, mp3s, and streaming music, but since he is a bass player and could use a low-volume practice amp, I opted for the Mobile Cube. He loves it! Says it works amazingly well and allows him to bring his tunes wherever he wants to go. Score! THEN ... this past weekend I swiped it from him for use at an outdoor hippie festival. I spun the Mobile Cube onto a mic stand, plugged in a mic (xlr mic with an impedance matching transformer/converter to 1/4"), and an instrument cable, put in six new batteries, dialed in a bit of reverb, and let a whole series of performers use it over the course of an afternoon. This is the first year that the festival had any sound reinforcement at all, and the reaction was overwhelmingly positive. The Mobile Cube made it possible for a solo singer/guitarist to be easily heard much further away than usual. This allowed each performer to concentrate on sounding good -- rather than concentrating on singing and playing as loudly as possible -- and it allowed many dozens of people to enjoy the music rather than just those who were seated directly in front of the performer. I got many compliments and many reactions like "Wow, that thing rocks! I gotta get one of those for ..." If I could make one wish for this thing, however, it would be that Roland would put an output on it, so these amps could be daisy chained or used as a proper personal monitor. But aside from that, it's totally awesome. (I'm probably going to buy another one so I don't have to keep borrowing the Boy's! I _know_ this thing is going to get used a LOT.)

Classic Vibe Box!

I can't believe the vibe of this little amp. It reminds me of the old am/fm stero radios but does it's small size fool you. It's like a small version of the Roland JC-120 on the clean setting and on the overdrive and distorted, it does that great too. You can hook up a mic, a drum machine and guitar all at the same time--and it balances out the sound. It doesn't favor one or the other. The chorus is lush and realistic. This is the most utility of all the little amps I've seen. It really has high quality sound. I've been playing over 30 years and know tone. It has tone; in fact, it has classic vibe!

I travel around the world a lot. I am just in from Japan. I am so happy that I was reading the guitarplayer mag. And saw the cube. And I went out and order it right away.P.S. The only problem I have is the battery do not last very long. For all of the inst. hookup. I though the cube would be like the Fender can amp. It charge for 3hr. playing time without battery. But I love it anyway. I use it everyday.
