I just bought the ULtrasound AG-30 Acoustic amp...I wasn looking for something pretty portable but sounding good and inexpensive..I haven't recieved it yet, but all the reviews I've read say give it a 9 or 10 with great sound....Does anyone own one?

Hi guitarman...
I own two UltraSounds, including an AG-30, and they are great.

Its just fine, for the price. It has a limited feature set and poor dispersion. On the other hand, it sounds good and handles a lot of different sources well (but not all). For $200, you can't get everything.

what's limited about the features and what is poor dispersion?

The AG30 has no effects and is only a single channel. Other than that I'm not sure what they're referring to. I have the AG50DS2 which is 50w and has two channels and 16 efx. I also have the DI Plus. I think they're both great. For the money, there's not much you can get that's better.

Nelson answered the first part of your question. Dispersion is basically how the amp spreads the sound out from the speaker(s), vertically and horizontally. If you stand directly in front of an Ultrasound amp (say 10 feet out in front), you hear all it produces, highs, lows and midrange. This sounds the best. However, if you stand more than 20 degrees or so off dead center, to the left or right, the tone changes - some of the frequencies are not being sent to your ear at the same strength as other frequencies. As you get further away from dead center, it gets worse. That's poor dispersion.

There are reasons why Ultrasound amps do this. Part is the design of the box to obtain more bass response. The amps use a baffle and set the speakers back a bit. That increases bass response, but the trade off is a fall off in dispersion. Plus the 8" speakers in most Ultrasound amps are coaxial - that design limits dispersion of high frequencies.

It's not the end of the world or anything.

Hi Nelson...
I have both an AG-30 and AG-50 as well, and I don't know what the post on limited dispersion is all about (I read the post explaining the statement). It is more of a feature than a limitation.

And there are no effects, which is a plus. At that price point, any effects which were included would likely be cheesy. I don't use effects on my acoustics when I play live.

The UltraSound, and the AER are both rather uni-directional which makes them great stage monitors. They don't leak into everything else. They are not intended as ''reach out and touch the audience'' speakers, though they do fine in small to medium coffee house environments.

The UltraSound are one of the most natural sounding of the amps I auditioned - very ''un-ampy'' sounding. I auditioned Shanendoah, Marshall, Fishman, UltraSound, Crate, Behringer, and AERs. I chose the UltraSound because they met my criteria of sounding natural, being affordable, and not weighing in at over 20 pounds.

Come on Larry, you know what dispersion is. And you seem to agree that the Ultrasound amps have limited dispersion. You make a good point that this means they make good monitors. As a main source, for an audience, that doesn't work as well. Two do just fine, on stands, or otherwise raised up. Like I said, the Ultrasound's dispersion performance is no big deal. Sorry to rain on the Ultrasound love fest.

Hi SDR...
I certainly do know what dispersion is, and as I said, Ultrasound is no more limited than the AER in this department. The AG-30 not intended as an audience unit for a large situation.

Actually few acoustic amps are. Possible exceptions would be the Bose PAS, Behringer, the Loudbox, and the Shenandoah and a couple other hight powered rigs. They also sport price tags in the $700-1200 price range and weigh in at 40-60 pounds.

I didn't think you were raining on anybody's parade.

The original post just asked if the $200 AG-30 is a good acoustic amp. It is.

The dispersion aspect is easily handled by lining out to the PA system in a larger venue. I find the AG 30 and very intimate amplifier with a very natural acoustic guitar sound. That's what I was searching for when I chose it. It's light,sounds good,records through the line out extremely well and being designed as an acoustic preamp specificly makes it easy to tweak for different guitars. In smaller places I've even used it with a small mixer for vocals as well as guitar. Their larger models have more bells and whistles and share the same sound quality but for my purposes where I need just a bit of amplification the AG30 does quite well.

I originally bought the Fender Acoustasonic 30DSP and I find that it is one of the good amp out there. Two channels with all the effects you can think of.
However, it was heavy to lug around and with all that buttons and knobs to which it will take time for me to figure out. I returned it and bought myself the AG30. The Fender was good but for my talent and purpose I thought the AG30 is far better to serve me at half the price.
One of my friend thought I made a mistake for trading it, but others say differently. I think you made the right choice and even if you didn't, I am sure you can sell it and there are a lot of people will be glad to take it off your hands. JMHO :)

thanks for all the input...I was just asking a simple question...I am basically just using it for my bedroom practice...playing with a couple other guys in a quiet practice room...I dont' need any effects on my amp..I have a danelectro chorus-trem Wasabi, and a Boss Flanger....good enough for me...I do need a reverb pedal though....other than that..it should be a good light acoustic amp, that sounds natural and easy to carry around.....looking forward to getting it on Tuesday....thanks

Try the Line 6 reverb pedal it got great revues. Although I have not tried one myself I am so impressed with the Line 6 stuff I have tried I would recomend you try one out.

I'm looking at getting one of these to use as a monitor for acoustic guitar and then to run out to the PA system.

Is everything still the same about these amps 4 years on?

I've had one of these which my son now has and uses with his Taylor GS7 (with K&K mini installed). For the money and in case you ever wanted to use it in a living room jam session or coffee house setting, I don't believe you could get a better sounding and nicely made acoustic amp.

Hi Paulů
As far as one can determine, it is the same amp as when it was introduced over 5 years ago.

Kind of one of those ''if it ain't broke, don't fix it'' kind of amps...still the best bang for the buck in a pro-grade amp in an affordable package.

I have the AG30 and it is a great amp for the home and works great live since it has a DI out to a PA, Mixer, etc. It is extremely well built with great components. The preamp section is great and again if you ever need to fill a room makes for a great DI.

For me, the AG-50 DS4 was a better choice, but then my needs are a bit different. The choice of our equipment should be based on what we need, what we can pay for, and what we prefer. Of course, these will be very different from one person to another. Sounds to me like you did very well indeed.
