Feature:
I set it up in coffee shops, using the attached tilt-back legs, and it always fills the pplace up, even when there are a lot of people talking, coffee machines blowing steam and so forth -- my music cuts through everything, and if I don't turn it down a bit, people at tables can't even talk to one another easily. Heh.

Quality:
By the way, anyone who has tried to use a GUITAR AMPLIFIER for voice amplification can tell you that it never sounds good. But the Ultracoustic ACX1000 makes your voice sound as good as it can possibly be. A real acoustic amp, like this one, is what's needed for both acoustic guitars and VOICES. If I had a Chicago-style (i.e. electric) blues band, I'd get an ACX1000 (or two) for the lead vocals and backup singers.

Value:
Ok, you get the idea. As someone else said, I went out and played all the acoustic amps before I bought the Behringer. If price didn't matter, this is the one i would have bought. It is louder and sweeter and more robust and more versatile than any of the others. And the price? Well, hey -- I was willing to pay less, since I had no choice.

Sound:
I bought the ACX1000 6 months ago, and have been using it heavily from the first day. It is beautiful sounding -- smooth and LOUD (120 watts total on 2 channels) and accurate. Voices sound super on condenser mics, and my electric/acoustic comes through powerfully, with a full, detailed sound, without boominess or muddyness.

Feature:
The chorus and reverb are great! The warmth control really works. The tone controls have good range. The TWO anti-feedback controls nailed my feedback problems without damping the mid tones. The pick attack control is good, but I find that the speakers have so much punch that I don't need it for my acoustic. However, it does help with my electric guitars.

Quality:
Everything works as promised. The amp looks cool too!

Value:
You can't beat the two full channels with pick attack, warmth control, double feedback notches, midi, 99 effects, etc.

Desirability:
Great amp - nice full acoustic sound, all the bells and whistles, looks terrific, and is not expensive!

Sound:
Great sound for acoustics. Just turn up the volume and your acoustic guitar becomes louder, including the harmonics. It is very transparent. I also works well with electric guitars. The only thing keeping this from a 10 is that the warmth control does add some hiss at higher volumes.

Support:
I have only had one question for Behringer so far. They answered my email promptly. I don't know what others are complaining about.

Overall:
I researched many other amps before settling on the Ultracoustic. You can't beat it for the price, features and looks.

Feature:
The foot pedal Helps alot. For the price there are no "least useful" features.

Quality:
It really loos kinda vintage and the Brass sides that make it lean are great.

Value:
Can't beat it!

Desirability:
Love the looks!

Sound:
Awesome sound for the price! I plug in my Ovation and boy what a Sound! The effects are great too.

Support:
Great support! Bought a B-unit first and didn't like the buzz. Returned and got a new unit with "NO" hassels! New unit sounds great, no buzz!

Overall:
I'm satisfied!

Feature:
Probably too many effects, but the ones I use work very well. I did notice the warmth meter doesn't seem to work. I've read that's a common problem and will be contacting the company about that.

Quality:
While it seems to be built like a tank, the outer vinyl is fairly thin. I've only had the amp out a few times, and already quite a few rips in fabric. The dials are plastic, but that doesn't seem to be a problem. It might not do too well on the road however.

Value:
You cannot beat this amp for value - no way.

Sound:
Amazing lush sound, responds very well to my playing style. I usually only use reverb and echo for guitar, and reverb for vocals - rates quite well against other products. Use it for solo gigs in restaurants, etc.

Ease of Use:
Nothing complicated at all. I think the folks complaining about hiss aren't using their gains right. Plus, this amp isn't for real loud playing. Anything setting at max will naturally give you problems.

Overall:
This amp meets my needs, whether as a solo performer or in my duo. The whole "made in China" thing is a little dramatic in my opinion. It is Germany technology that counts. I'd replace this amp in a minute if it were lost or stolen. The only downer for me is the weight.

Feature:
Beautiful complement of features. Well thought out. The meter is useless but if you're into how your amp looks, it's a nice visual touch.

Quality:
Damned heavy amp, appears to be built like a tank. No rattles.

Value:
No way would you get anything even close to this for the money. Take a look at a $300 Marshall amp if you doubt it. This amp's construction reminds me of my old Twin Reverb. It weighs as much as an outboard motor and will probably survive a fall off the back of the truck.

Sound:
Overall the sound is clean and crisp. Distortion only occurs if you really bang on the instrument or turn up the input gain too high. At higher volume levels the feedback controls are very useful, but the notch filters could use some width control as they tend to dampen the overall sound. Still, for the money, it's hard to argue. Sounds remarkably similar to a competing amp costing $800.

Ease of Use:
Excellent interface, easy to operate, didn't need to consult the manual to do anything, it's all in your face -- as it should be.

Support:
Asked one question via email, got an immediate reply, based on my limited experience I'd have to characterize their support as very responsive and friendly.

Overall:
Very satisfied, I bought the amp used for $175 and I could not touch the sound, construction, or feature set for anything less than 4-5 times the price. Apparently, slave labor equals low retail.

Feature:
Loaded!

Quality:
Built like a rock!

Value:
Feel free to compare it to Marshall, Genz Benz etc... This amp is a gem and probably worth $1000,00 if it was built in Germany.

Sound:
Amps are all about the guitar you plug into it. My Taylor T5 loves it, so do all of my high end guitars. I also use it with a V-AMP2 and she rocks!

Ease of Use:
Read the manual, learn how to use it right and voila!

Support:
Mine is a 2006 and have yet to have to call anyone.

Feature:
Lots of cool features on this amp....And I use them all.!

Quality:
Looks to be built very well. I had mine shipped via mail, and it looks great. I havent used the legs yet! we will see!

Value:
Just cant beat this for the price!!

Desirability:
I just had to have this.

Sound:
I just bought this amp and currently play a Taylor 310CE through it. I found the sound to be very good. I also have played for years and played many different types of amps, but this one really has a good sound. I would recomend this amp for any serious musician.

Support:
Never used it yet...hope I never do!

Overall:
I am very happy with this amp would buy it again and again. I have also suggested to my student to purchase one.

Feature:
It has everything I need

Quality:
This thing is built like a brick **** house

Value:
Best value of any amp I've seen or tried

Desirability:
Looks like an amp should look

Sound:
It really sounds great , very good effects,It does have a slight noise when turned all the way up, but for my use I dont need a lot of volume

Support:
Never had to deal with them

Overall:
This is all I'll ever need
