Roland Mobile-AC Portable Battery Powered Acoustic Guitar Amplifier

I use this for ukulele and vocal performing in small to medium venues. It is great that it is battery powered (I also have an AC adapter). I have a mic stand setup with mic, iPad holder, uke holder; I can hang this little amp from another holder, and then I have a self-contained performing rig. The sound is OK. It is loud enough to fill a large sized meeting room, but it is not powerful enough to fill a gym or auditorium. In a group, it is good for reinforcing the sound. Our performance group uses many of these at one time, and together they raise the volume of the entire group. It has three inputs that I use: vocal, instrument and aux. It's kind of old technology (no Bluetooth), but it works great. It's so small that on an overseas trip, I put it in my check-in luggage.Negatives: the mic input is 1/4 inch, not XLR, so remember to bring the right cable! The vocal volume knob has gotten tweaked on mine so it doesn't go low any more. This amp has lived a hard life, so that is acceptable.

Update: I've had this little amp for about 8 months and have quite a few hours on it. I've used it with an acoustic guitar (Taylor with ES2) and electrics, in both single-coil and humbucker flavors. The acoustic gets plugged straight into the "Guitar" input. When I use it with my electrics I usually split the signal, run one leg straight into the "Guitar" input and the other through an overdrive pedal into the "Voice" input. That gives me the option of playing clean or with OD. I mostly practice to backing tracks; I plug a my computer or phone into the "Audio" channel via a 3.5 mm cable. I especially appreciate the individual channel volume controls, they make it easy to balance the Guitar, Voice and Audio channels. It's a decent little basic amp with plenty of volume and while it's small speakers can't keep up with my regular, 12" stereo amp setup, I'm totally happy to practice on this little guy. Just remember, it's clean tones only, no distortion unless you stick a pedal in your signal chain. It does have a chorus button for the "Guitar" channel but haven't bonded with that effect. Can't say too much about battery life, it's usually plugged into AC. PS: I ordered the "no handle" version of this amp and was pleasantly surprised to find it shipped with a web carrying strap which I prefer anyhow. I'm pretty sure the hard handle would have been in the way of the knobs.

I got this to take on vacation so I could practice and perform my Hawaiian Steel Guitar lap steel. The tone is wonderful for this instrument. Please take my review as positive, but there are things I wish were better.1. The aux input shares the tone setting of the guitar input. The steel guitar needs the tone setting at a minimum. I use a backing track and my backing track loses all the high frequencies.2. The headphone output shuts off the speakers. This makes sense but I wish there were an option to hear the amp and send a line out to a PA.3. I wish the mic input was XLR for a pro microphone.4. I wish there was a rechargeable feature.

Got this as a b-day present for girlfriend who plays keyboard and sings several shows a month in small intimate settings. She is tiny and most often leaves her heavy Korg piano at home and uses lightweight keyboards. She wanted something to beef up the sound of her el cheapo light keyboards. She had been using a $300 keyboard amp on wheels till it failed. She says this little Roland has better sound. I agree. It will not sound as good as a first rate amp combo or PA, But it's so much better than the speakers on the cheap keyboards. The vocal sounds pretty decent through a Senn 835. I think that this unit would be great as a monitor. Despite the significant limitations with EQ, when I ran a signal out the 1/8 inch head phone jack and split out to 2 1/4 inch mono and into both inputs of my Alto TR212 powered speaker, the results were astounding. Truly jaw dropping. Apparently, here are some nice pre amps in this tiny unit. Used this way, vocals sounded better than my Soundcraft board. With thoughtful speaker placement, I suspect a duo could have great sound using these en lieu of a board and monitors. I'm getting one for myself. Always seem to appreciate Roland quality and designs. Incidentally, I paid only $109 on Amazon for the unit. (open box)

I used this little amp as my only busking amp for about a month. You would be shocked to hear the quality of the sound it puts out.. you aren't going to fill an auditorium with music of course but it worked very good out on the street. Before I bought this amp it was just me and my guitar with no amplification. My tips TRIPLED on the first day!!! Took my about 3 weeks to make the money off this amp to buy a bigger one. What I'm saying here is that this is a pretty good buy... It's not as big or as loud as the Street Cube but for the price you just can't beat it!!! Shoot, I'm glad I took a chance on it!!! I bought a Roland ba-330 with the money I made with this one, and mics and cables etc... Good stuff

I mention Mickey Rooney, because this little unit enables you to "put on a show" anywhere you like.And like Mickey, despite its small stature, it packs a punch and has some serious skillzzz.I don't think I have ever had any new gear surpass my expectations, as much as this little busker.Definitely voiced for an acoustic guitar and microphone.Separate inputs for each. Separate volume controls. Shared reverb and chorusReverb is decent.And the chorus, which I normally don't like, is superb.This unit is totally quiet.Even when using both the microphone and guitar. And I don't know how they did it, but it is extremely feedback resistant. Even when you push the 5W to the max.And I have been using this nonstop, in my home because my acoustic guitars sound absolutely fantastic, through this little amp.The only dedicated acoustic amp I ever had was a fender acoustasonic junior. It was pretty good.But my D-28 and J-45's both sound heavenly, through this lunch box sized over-achiever.The best $129 I have ever spent.PS. It also has a 3rd audio input, which also has a separate volume conttol, if you'd like to play along with something from an outside source.The only thing I miss are seperate reverb controls for guitar and mike. But the combined reverb gets the job done.can you say STEREO?Yeah Baby.Roland Beethovan![...]

I was a little skeptical... It is a small unit, but, it packs a good punch. I play a Classical/Flamenco Guitar using an external, cordial, microphone and could not be more pleased with the performance. I was able to take my Sterling Mic, attach it to a two channel USB Pre-amp (M-Audio MobilePre running off a USB battery pack), connect Pre-amp to the Roland (also running on batteries) and run completely off grid. Awesome - Everything comes in under 15 pounds with batteries, and yet, still had more then enough power to play a full set.I played a smaller piano bar last night with the new rig. Bar was 24 feet wide and 120 feet deep and the Roland did just fine. I had to play a little with the Gain and Mic but that happens to all external Mic rigs. I was worried that a hard hit flamenco roll would top out the speakers, but, the Roland hung tight and replicated the sound far better than I expected. I even had other guitar players, from the audience, come up later to take a look at the setup, and the little Roland Amp. Highly recommended.

Played for years in bands playing through Fenders. Since that has wrapped up, play now at informal settings. This amp works great. It's size, volume it can put out, tone & light weight all make it a winner. Short update: Been playing at a condo association on Sundays where they have a sound system for the voices. With this amp I am right up there with the sound system. It sounds so nice to be able to be at the same volume.

Ho acquistato questo amplificatore stereo per utilizzarlo principalmente come cassa monitor per il notebook, dove svolge egregiamente il suo lavoro. Non ho resistito alla tentazione di provare ad usarlo anche come amplificatore per chitarra classica amplificata e di paragonarlo all'Acus che adopero normalmente: non sfigura neanche poi più che tanto, il suono è solo un poco più metallico e manca della morbidezza che caratterizza i prodotti di quel marchio (che comunque costano assai di più), ma si lascia ascoltare gradevolmente. Unico particolare irritante: la politica della Roland di non inserire nei propri manuali informazioni essenziali come la polarità dell'alimentatore (non fornito di serie) per farlo funzionare su rete elettrica. L'informazione è comunque reperibile altrimenti.

Great little practice amplifier. Love it!

This thing is very portable and powerful for its size as an acoustic guitar amp. There is absolutely no problem in performing for a small crowd such as when there is friend and family gathering during weekends. It requires 6 AA batteries for which I use the famous rechargeable Panasonic Eneloop and that would last for days with one full recharge. Dura cells won't last that long....I am writing a review almost after 10months of use and this thing still works as good as new.....I have absolutely no regret in purchasing this little amp as it gave so much fun and pleasure while using it.

Very nice small speaker for playing any instruments , the sound quality is very good

Assolutamente fantastico! Suono potente per essere un 2,5+2,5w, chorus Roland superbo unito ad un reverbero+wide ottimi fanno di questo gioiellino un fedele e performante compagno per musica live nei locali. Prima di provarlo ero scettico ma vi garantisco che vale ogni singolo centesimo speso.
