I like this amp. It makes my Ovation Elite LX come alive. More than enough features and output for my home use. Very heavy, glad I don't have to carry it around. Electronically everything seems to be beautifully designed. However, I do not like the rotary pots and their associated knobs. When I can wiggle side to side a knob attached to a circuit board pot I think cheap. That has to put strain on the circuit board. The knobs need to have bigger shafts to prevent the wiggle. My low end Behringer amp has very solid feeling knobs. Can't imagine why the high end model would use such flimsy feeling ones.

Less than 20 min after opening the box I was on the phone with Musicians Friend to return it.

I intended this amp to go with my Les Paul Ultra III for the acoustic pickup, but the sound was brittle and tinny. When I put the Ultra III through a DI or even my Fender Mustang I got a full rich acoustic. But just to be sure I tried my Taylor 814. Surely the 814 would be fine. Nope! It sounded like a $49 Walmart Guitar.

Also the volume was non-existent. Cranked to the max it barely got over the acoustic.

The onboard FX were terrible and limited.

On the upside it was a pretty brown color with a nice gold face and nice looking (but cheap plastic) hardware.

I can't really think ANY reason to buy this amp. Stay away!!!

I have a Behringer ACX 1000 that I have used for a few years in my 1 man acoustic act and I have an Ovation LX that I play and it sounds great and has a lot of punch through it, and the vocals even sound good. It recently developed a buzz so I decided to buy the ACX 1800 because it had 180 watts and thought that with all of the EQ, EFX and Feedback control that it would be a better amp for me. Well I was wrong! I just got the amp and noticed right away the size difference between the 2 amps (the 1800 is a lot smaller) and thought, I'll give it a try and see if it compares in sound quality. I plugged the guitar in and turned the volume to 3 and had no sound. I new it wasn't a cord issue so I turned it up to 6 and could barely hear it. I then turned it up to 8 pregain and 10 master and could not believe how thin the sound was. I tried to EQ the sound but it distorted real bad. In all actuality this amp doesn't seem to have 30 watts! Maybe I got a bad one. I don;t know. I boxed it right up, called Musicians Friend and they said no problem and sent me a return label. Thanks Musicians Friend! You are what you say you are. A true MUSICIAN'S FRIEND!

I have the, "Behringer Ultracoustic ACX1800 Acoustic/combo Guitar Amplifier". Well at first this amp was great but, after a few months I noticed a buzz in channel 2, this turned into a hum, and mid range went out in both channels, so the sound quality went down allot. Now me, Im using this amp in a small room so it isn't turned up very loud, still I figured this amp would last along time, which it didn't all theses problems I listed happened 6 months after I bought this amp, so for me this amp is a disappointment.

I own this little gem of an amp. I use it in much the same way as 3 Dog Music, although a little differently. This amp doesn't have a lot of power output, especially for larger clubs or venues, however this is easily corrected. I also use it as an acoustic guitar monitor, and I use a good condenser mic in front of the cabinet speakers which then runs through a tube pre-amp and then into the soundboard. This is where I get the volume needed when volume is needed. It is very clean, noise-less, and produces a very accurate acoustic signature for each of the guitars I use on stage. I usually place it to the side of me about 10 feet away and use an amp stand to angle it so it's pointing straight at my head rather than by legs. It it makes a perfect guitar monitor and running it through a tube pre-amp before it gets to the mixer board, lets me adjust the pre-amp to match the output of the Behringer amp. It truely gives an accuate, clean, noise-less reproduction of an acoustic guitar. I could not be happier. By the way I went through at least a dozen acoustic amps before I got this one and is by far the best one I've owned for acoustic amplification.

I play swing style guitar with a horn band and this amp works well with this. It provides a nice ? clean ?. acoustic/electric sound. The effects are suitable and I am very happy with the quality of sound. I have used the microphone connection only twice but it was sat with the environment. This is not something to be used if you want a big sound with a vocal group ? for that get a PA system ? but for one or two people with a guitar it does well in quiet, listening settings

I currently own both the ACX900 and the ACX1800. I bought the 1800 because of the extra power output and the adjustable parameters for the effects and also the compressor. I felt very let down by this amp last week when I gigged with it for the first time. When I set up before we got started, I expected to use the 1800 because I sing lead and play lead guitar in a 3 person acoustic trio. I was to let our backup singer use my old 900 and the other guy has a 900 as well. Side by side comparisons lift me shocked at how different these amps are from each other. The 1800 lacked the volume big time and the fullness and bass response were nill. The vocals distort much, much too easily. The compressor works well but nothing could even bring this amp close to the quality of the lower wattage ACX900. I decided to use the 900 for myself at the last minute and set up the 1800 for our female backup singer so the vocals wouldn't distort much but we got a lot of complaints that nobody could hear her. The instrument channel sounds a little better in my opinion on the 1800 but neither channel will give you anywhere near the volume or bass response as the 900. I just purchased another 900 for this weekend's gig and will be returning the 1800.

This thing is one clean machine. I use it with my top quality Gibson's & and other top of the line acoustic's in room from 75 to 175 seating cap. And it fills the room nicely. I was worried about a good bass end with such small speakers, but the closed back does the job. I do place the amp on an amp stand to get it off the floor and project into the room. There's no sense trying to play at someones feet. This is not a muscle amp, but it is a true projection of the instrument that your putting into it. When I need more kick for opening act slots and larger venues,I do use the direct line outs into the main sound system and use the amp as a monitor. I set my level and tone then give it to the soundman. No buzz or hum. Just a clean signal to the board. I'm about to purchase the second one for each side on the stage.

This amp has all the features that one could ask for; i.e. 16 adjustable effects on both channels, and tuner mode that silences the amp, and a two button foot pedal to control each channel. The sound is dead on, except when I turned it to the maximum to hear the full power, I got a slight buzz from the feedback suppression. I know that it is not as loud as 180 watts is expected to be. This amp is more like 60 to 80 watts for each channel. I had a Behringer GX112 Blue Devil that was 60 watts and this amp is comparable to that. I think the mistake is made when consumers believe that the instrument channel is 180 watts, which it is clearly not. This amp is great for someone playing a small cafe, quiet bookstore, or a bedroom, but do not expect to go on tour with an inexpensive PA. Play it before you buy.

I have been using this amp since summer 2007 and I have to say it's performance has been incredible. I know it's called ultracoustic but acoustic or electric or my 6 and 12 strings I mike with a condenser mike and pre-amp the sound is awesome. The fx's are great and it has plenty of watts for playing club gigs. It is great not having to lug a pa system around. The craftsmanship and attention to detail have made me a lifetime Behringer customer. If you need a good, solid, versatile amp, buy this one you won't be dissapointed.
