    Playing over 50 yrs. Everything except Rap/Gangsta.


    I've had this about 3 weeks and I just want to play with it all the time. It's friggin' awesome. Let's be frank - it's not a Marshall stack or a Twin but it makes my Taylor sing. The classic Roland chorus, adjustable reverb . . . I have been setting the volume a tad more than my unamplified sound. SWEET! I have "cranked" it a few times - sounds good. Not overly impressed with the microphone however I am using a high impedence Shure that is over 40 yrs old. I usually play about 2 hrs/day; now I have to make myself stop. For just sitting around and playing guitar I can't say enough good things about how wonderful this sounds. I've been using batteries but also got the AC adapter.

    Small Amp with Huge Sound

    I wanted a small amp that I could take anywhere with me that I could use batteries with but also had the option of a power cord. I wanted a rich sound not a cheap tin box sound. I talked with my Sweetwater Rep Devin Cunningham & he recommended the Roland Mobile AC amp. It is only 5 watts but it definitely sounds like more than that. It has reverb, jacks for your mic, guitar and a cd trainer or other device of your choosing. This amp is small and weighs under 6 pounds so I can conveniently take it outside to practice and on trips. You will not be disappointed in this amp if you are looking for a small amp with a great (huge) sound.

    Really nice!

    Really a nice little unit! Plenty of power for mild amplification to acoustic sound. Battery life seems good but I ordered the AC adaptor anyway.

    Excellent Amp

    For the small size and price range this amp far exceeded my expectations.

    Jam Equalizer

    I use my Mobile AC Acoustic Combo Amp as a monitor to enable my soft voice and acoustic guitar to be heard in a group of mostly electric instrument players. It seems to help them remember to back-off excessive amplified noise.

    Roland Mobile Acoustic Amp

    Even though it is only 5 amps, this little box is sufficiently powerful to work a small room. Small and easy peasy to transport. Easy to use, like that I can plug in my iPad and play along with Eric Clapton's San Francisco Bay Blues! Use it for our Uke group of 50 people. Didn't realize how much I would like the battery option. Controls are simple but effective.

    Comparison with Mobile Cube

    Remember: the Mobile Cube AC is not the same unit as the Micro Cube or the Cube Street...

    The Roland Mobile Cube AC (MCAC) just arrived, and I spent a short while comparing it with my Mobile Cube (MC) (how complicated can it be?). Guitar is nylon string Takamine TC132SC.... CT2 preamp, etc....

    Impressions: the sound is quite acceptable; not as rich or detailed as its bigger brothers, but quite useable. Reverb and chorus are fine (the reverb at its max setting is even a little "over the top", and should satisfy any surf freak....

    The interesting part came when I compared it to the Mobile Cube....

    The MC (Mobile Cube) had a bit of noise even with everything unplugged, effects off or at minimum. The MCAC was silent as far as I could tell....

    1. First I checked out the audio in. The MC seemed to boost the mids substantially by comparison (and then cut them substantially with center cancel turned on). The MCAC sounded much more natural, and much better for the percussive backing tracks I use.

    2. Guitar In - I only compared the MCAC with the Acoustic setting on the MC. For my Takamine, the sound was a bit "ringy" through the MCAC (even with chorus and reverb off), but sounded much more natural than the MC, which emphasized the mids as mentioned above. (Initially that was acceptable to me when I first got it, because I was trying to get rid of the bass from the SBT I was using...) There is a very slightly discernable piezo "quack" that is unnoticeable in my bigger amps (AC-33, SA-220, A-Ref) except a very loud volumes (which I seldom use); of course that may be an unfair comparison, since a low volume for the bigger amps may correspond to a loud volume for the MCAC).

    3. I particularly like the volume adjustment for the backing track (audio in) on the unit itself, so I don't have to fumble for the mp3 player....

    I'm not sure it would be loud enough (without distortion or quack) for busking, but if you just need an enhancement of your basic sound, rather than full on projection to a crowd, I think it would be quite sufficient (i.e., might work in a subway, or coffeehouse if the crowd wasn't too big or noisy) For practice, it is great.

    I didn't check the mic, because I don't sing that much anymore, unless it is Flamenco (because the crowd is going to dissipate pretty fast if I do....:-). But I would imagine a difference, since the audio in's were so different.....

    Great Addition to the Roland line....

    This amp is a great addition to Roland's line, with a great form factor for its intended use. I play a Takamine TC132SC nylon string, and while the sound is not as rich as the AC-33, it is still quite acceptable. Backing tracks sound fine, and I like the fact that the volume is adjustable from the top, instead of having to fumble with the mp3 player

    The chorus and reverb are good. The quality of sound is much better than the Cube Street for my application. And it does sound better than the Mobile Cube on the acoustic setting (although the latter is no slouch either).

    Although it doesn't have the richness and detail of my Fishman SA-220 or LR Baggs A-Ref, it is quite useable, and fits perfectly in the sportpack on my motorcycle (I use a BR-80 for backing tracks)..

    For me, it is a keeper.....
