Used this amp for the first time for a resort gig in a medium size ballroom. Played it near maximum volume with no audible distortion. You wouldn't want to play a large room with this amp but for small to medium size venues it's great. Really nice acoustic guitar and voice tones with a good mic. Amazing reverb and chorus. The on board loop station is lots of fun and easy to use when you have the FS-6 footswitch. I find that most loopers have a slight delay in the switches when starting and stopping but not this one. This amp is perfect for solo artist doing small to medium size gigs.

Nice features. Well made. Sound quality needs to be improved.
Lots of features. Two channels with full eq and volume. Phantom power. Lots of input and output jacks on the rear. Nice effects. Very light and portable. And it has a looper which is fun. I have a Roland AC-90 which is really great. The AC-33 is like a mini AC-90 with all the features and more, except for the sound. I hoped it would sound similar to the AC-90, just maybe not as loud. And it wasn't as loud, and I was not impressed with the sound, especially on battery. It probably would benefit from having a tweeter/high frequency speaker. The full range speakers just don't cut it. And the battery power feature is a great idea. You can use AA batteries, but again, the amp may have sounded better with a better power supply, maybe something rechargable.
The AC-33 appears to be built well, as are most Roland products. No cheesy knobs or jacks. And everything seemed to work as it should. But the quality of the sound was not there. This was actually the 2nd AC-33 I purchased. The first one sounded pretty much the same, The sound with the AC adapter is okay, but it goes downhill with batteries. As the volume goes up, sound quality goes down. If you push it a slight bit too hard, the sound breaks up, and it appears almost that there is a limiter on the output. I find this disturbing, and I think it makes the amp less useful. If you are using it on battery and the sound clamps down, what's the point. You need to be amplified and heard. Might as well go full acoustic.
Well, if the sound quality from the amp was much better either on AC or battery, it would be a good value, although a little over priced. And I'm always willing to pay a little more for Roland quality. But this amp just doesn't deliver.

First amp I have ever owned. Choose based on recommendations from other ukeule players. The Roland name speaks for itself and the fact I can use it on gigs with no AC power is a big plus. Very happy with my purchase

      Comments about Roland AC-33 Acoustic Chorus Combo Amp:

      Just received this small acoustic amp, and I am happy with the amp overall. If you are reading this on the Guitar Center website, then check out the earlier reviews as they are pretty much spot-on. The amp sounds great, but at 15 watts per channel, it is pretty much limited to smaller spaces. It can be used in larger venues with the line out.

      The amp is very portable, and could be useful for someone busking with an understanding of the limitations. The amp cannot put out enough volume to overcome noisy environments or reach out to a larger crowd. A quiet little jazz bar, home concert, or other small room would be OK, but I found that I had to turn up the master volume and channel levels almost all the way to fill a room with sound (depending on the acoustics of the room). By small room, I mean 10 x 15 carpeted or 25 x 30 hard surfaces/vaulted ceiling as examples.

      What is there to like? The sound quality is pretty good. I did like the 'Ambience' option, but like reverb, this could be overused and get tiring too. The portability is nice, again, if you consider the limitations while under battery power. The looper is pretty good, but you need a footswitch to get the best use out of it and it is temporary unlike a dedicated pedal. The amp does not have an effects loop, but most users probably do not need that option. I have mixed feelings about the battery pack as it is functional and well built, but an improvement would be to re-charge batteries without having to remove the pack. Hard to be too critical since the design is pretty good outside of that concern.

      I have had several acoustic amps over the years. All have their strengths and weaknesses. I would recommend this Roland AC-33 if you are looking for a small portable amp and understand the volume limitations. I would seek out other options if you are looking for more volume in environments with more ambient noise or greater space. Personally, I like the amp and think it fits my situation.

        Comments about Roland AC-33 Acoustic Chorus Combo Amp:

        I absolutely love the Roland AC-33 Amp! This is my first amp and may I say I couldn't be happier. I am a harpist and was told acoustic amps were the way to go. The quality is phenomenal and the effects are great! Using a little reverb gives a great tone, almost like being in a large concert hall. The amp itself gets really loud and I love that it is light weight and small. A harp is large enough to move around, this is the perfect size for gigs! I used a K&K "Triple Big Shot" Harp Pickup with a preamp into this Roland amp and wonderful results! Highly recommend this amp.

          Comments about Roland AC-33 Acoustic Chorus Combo Amp:

          I have owned this amp for about 5 years and I have done over 500+ gigs with it easily. I have other similar products that I use depending on the size of the venue but this is usually the one I go to first because it sounds the best. Most amps with seperate tweeters are artificially brittle and not very flattering to piezo pickups. The AC-33 is crisp and full but not brittle!. The looper is brilliant! The batteries last a long time but you get better headroom when you use the veary hearty AC adapter. The Feedback reduction is also very effective and does not kill the tone as some do. I use this amp constantly, it is a gig workhorse. For larger venues, it works well as a monitor and a line can be sent to the mains so it acts as a mixer on stage. The only thing I am not crazy about is the vocal mic input but it is good also, just not brilliant.
          You really need to crank the gain on the vocal channel to get the signal because it is a multi use input and padded for versatility. No points off for that. The build quality is
          Typical Roland- the best you can find. I would replace this in a second if it broke but it does not seem it ever will. It is worth every penny of the price, so buy it. Oh, BTW- I think of the series of AC amps, the 33 is the most natural sounding, not boomy and not brittle. It is GREAT for nylon string and other acoustic instruments also. I use it for UKe and Banjo too. Probably one of the BEST purchases I ever made.

          This amp is fantastic. You're not gonna take it to say a "Woodstock" but for the smaller venues, get togethers, bars, coffee house, parties and jam sessions it has more than enough volume! For lager venues just run the output to an AC 60 or AC 90. The sound is just fantastic! I couldn't be happier with this purchase.

            Comments about Roland AC-33 Acoustic Chorus Combo Amp:

            Great build quality. Strong clean sound. Use it in accustical performances (Old time/Irish) to give the guitar a little lift to match the bowed instruments in volume, and also as a guitar/mic combo for solo performances in small venues. Totally fills the bill for each. A little dissapointed in Reverb/Presence quality but certainly not a deal killer. Chorus is perfect and looper comes in handy for basic stuff. I'm playing a Taylor 514 with an L.R. Baggs M1A pickup. Very happy with this great little amp.

              Great little pro amp-Compared with Fishman Loudbox mini, and ZT Acoustic Lunchbox...

              By BEN WOODS

              from Long Beach, CA

              Comments about Roland AC-33 Acoustic Chorus Combo Amp:

              Always looking to downsize, I needed a new amp that was nice and small. I'm a professional Flamenco Guitar player and I needed something that I could do my smaller gigs where I provide "ambiance" in wine bars, restaurants, county clubs, hotels, weddings, etc., but also something that could handle a flamenco situation (with singers, dancers palmeros, etc.). I bought the Fishman Loudbox Mini, the Roland AC-33 and the ZT acoustic Lunchbox and tryed them all out right next to eachother in the GC acoustic room, and ended up going home with the Roland, here's why: Fishman Loudbox Mini-was great, clean and loud, and the reverb sounds fantastic (i am buying this one tomorrow for my Washington State gigs), but a had a bit too much midrange 'bite" and was quite a bit heavier, no battery function and is just kinda ugly. Wish they made it all black and discrete. ZT Acoustic Lunchbox-With all the hype and boasting 200watts I was sure I was going to love it. Nope, sounded terrible, at least with a nylon string guitar. Super small and has a lot of cool professional functions though. Roland AC-33- By far the warmest tone out of the 3. Best looking, and just as small as the Lunchbox, most lightweight too! Yes it has less wattage (30) but is almost as loud as the Fishman. I just played a wine bar with around 60 loud people and it did just fine with volumes at 50%. Handled my backing tracks too. The reverb, not as good as the Fishman (too platey) and I dont really care to use the looper or chorus much. But I can see the battery power really coming in handy for weddings and quick on the go gigs (I used to have a Crate Limo that I loved for it's battery but not for its tone). I have a 150watt amp for gigs I know will have 100 people or more. Or if it's a 500 person gig, I may just use the Roland and line out to the house or a powered speaker. In conclusion: Roland wins, Fishman comes in close second. The size, look, portability, and tone mattered the most to me with my purchase, for solo guitar gigging. Plenty of power for restaurant background music, small flamenco group, etc. When I am with a band, I would want to use something with more power. But the thing is cute and works great! No more rolley, just walk into the gig with a guitar on back and this in hand. If you get it, get the case by Arriba also. Holds the amp perfectly with room for your cables too.
