      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.

        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.

        Mostly Goods, Some Not So Goods

        By Jordan Armstrong

        from Ft Hood, TX

        Comments about Roland AC-33 Acoustic Chorus Combo Amp:

        My experience: Toured Afghanistan with an active Army band playing acoustic gigs with these amps. Setup was bass, two acoustics w/ vox, cajon. Performance: First of all the amp works how it's supposed to. It's incredibly easy to use, and it's small and lightweight while at the same time being VERY durable. It made it through a year of being lugged around the worst locations possible in a big TUF box in and out of helicopters. It was also able to adequately reflect changes in the sound produced whether it was a different guitar or effects. My Martin Dread sounded big and full and my buddy's Carvinstein sounded very cool with all his custom work and effects. How We Used It: We had two of them. Plugged acoustic and vox into each and adjusted our own settings/reverb on the amps and then plugged them into a few mains depending on the size of the room. If the room is any bigger than a small dining area in a restaurant you're going to want a decent main to pump out the total sound. They just aren't enough on their own unless you're playing a pretty small room. Issues: There really was only one, and I guess it's kind of expected. When plugged in these amps spoil you a bit because their performance really is good for what it's supposed to do. However, when you use these amps on battery setting the quality diminishes drastically, to the point where we weren't even comfortable putting out a product. It sounds almost as bad as an old Talkback tape recorder that I used to play with as a kid. It was that distracting. Bottom Line: If you're aware of what this amp should be used for (acoustic guitar/singing) and you do NOT expect to use it on the battery powered setting it's a good amp. Only count on the battery powered setting as an absolutely last step emergency.

        AC-33 A Beautiful Amplifier

        By jay vinton

        from Honolulu, Hawaii

        Comments about Roland AC-33 Acoustic Chorus Combo Amp:

        I actually wanted the AC-60, but with no looper or professional need, I chose to purchase the AC-33. Within 3 hours, I was making professional sounding loops and practice riffs. In the end, I saved over a hundred dollars by buying the smaller one and getting the momentary switch. The amplifier does not need to be dimed to sound fantastic. It has a full, lush, stereo sound that is only limited to the guitar at hand. I played several through it and admittedly some didn't sound as good, but the amp played them all flawlessly. The sound is "enveloping" and full, the stereo is very unobtrusive and just makes your guitar sound huge. The effects, unlike pedals, are more subtle, the ambiance setting is possibly my favorite to beef up the stereo and create lush sounds. I do run an Electroharmonix Memory toy pedal through it and you have to be careful of feedback due to it repeating the signal on playback of the looper. I turn off all effects for playback and it really does control unwanted noises. Having the Boss momentary switches are a must if you intend to use the looper and hit the mark. It does have buttons to start, overdub etc. but it just doesn't work as well without the Boss momentary pedals. It would be nice if they came with at least the small pedal and cord, those are extra ,after the purchase of the amp. Also, it would be nice if the padded bag was included or offered as with the larger amp. If it is, it wasn't mentioned to me and I actually asked the sales guy if it was included and he said yes, only to find out that it wasn't, that isn't Rolands issue but I have to put out a few more bucks for it. I chose the rosewood over black and am still evaluating whether I like it or not, but it is a finely made, well appointed amplifier that either DI'ed or mic'ed would be fantastic on stage. The Ac-33 will not keep up with a band otherwise. All in all, a fine amplifier that I A/B'ed against my existing Fender Acoustisonic jr. The volume is the same, but that's where the comparision ends, the Roland offers much more and is smaller and lighter. Added touches like the tilt stand are very nice. I was a bit taken aback by the warnings about the seemingly delicate rosewood finish. It should be more rugged. I'm Happy, and that's what it's about.

        Not a Allstar for all situations

        By Dan

        from LA

        Comments about Roland AC-33 Acoustic Chorus Combo Amp:

        The Amps Clean sound is beautiful in a small room, especailly in a musical demo room, where most of us try this out. You know that room that is 8x8 or 8x10 and sound proofed from the drummer next door. Yes this amp sounds great, but take it to the street, or small coffee shop and you dont have enough volume. If you play with a Piezo pickup , you can forget buying this amp, like a Woody, or ES-Go on the Taylor's new GSMINi guitar, forget buying this amp. No volume at all, but if your guitar has a pre-amp on board pickup, Okay give it chance. For a Gig go straight to a PA, or Mic it up with a dynamic mic. Pay special attention to what I mentioned, Piezo pickup on guitar is a no go combo with this amp for volume.

        Unbelievable Sound

        By Dan

        from Newport News, VA

        Comments about Roland AC-33 Acoustic Chorus Combo Amp:

        I was trying out different guitar amps with acoustic guitars at a music store and when I plugged into this it was instant gratification. The sound was rich and full, and blew away everything else. The chorus and effects were excellent, and the price is affordable and well worth the product.

        Great Amp!

        By Wayne E.

        from N. Charleston, SC

        Comments about Roland AC-33 Acoustic Chorus Combo Amp:

        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.
