After reading all the reviews, I decided to take a chance on this amp mainly for playing/singing solo gigs and trying to downsize my rig. It arrived today and I'll give my honest critique (pre-gig).

PRICE: I'm sure there is nothing better in this range, and most people will be satisfied with this purchase.

USE: If you are a professional accustomed to using higher end equipment, this amp will fall short of your expectations unless you employ some additional tweaking. See below for some suggestions.

CONSTRUCTION: Cabinet (closed back, a big advantage for both durability and direction of sound) is very robust and solid, However, it does make this amp weigh more than some would like it to given its small footprint. You definitely want a lightweight hand truck for this and your other accessories.

Front control panel controls are delicate. I would definitely get a custom cover made to protect the fragile 5 EQ band adjusters and knobs for level and click dial-up effects.

Front grill is velcro-ed to the cabinet rather than 4 corner screws- but that didn't seem to be an issue as far as the quality of the seal or any unwanted vibrations.

Only cosmetic criticism is that the back seams of the tan laminated material are not that tight or flush, so you may want to find a matching color to permanently tape them before you start banging it around.

SOUND: This is of course very personal and all depends on the guitar and mike you are using, and the kinds of venues you are playing.

In general, the pre amp stage of the amp is weak for both guitar and mike inputs.

If your acoustic-electric guitar does NOT have on-board controls for boosting overall level (and maybe filling in some of the frequency band gaps not covered by the graphic EQ), then I recommend some kind of pre-amp box like a Tech 21 Paradriver. Even if you don't click it ON to activate the EQ settings, the signal going to the amp is boosted significantly (at least 20db) and will take better advantage of the amp's power, which is considerable. If you DO click and activate the Paradriver EQ, you at least have the ability to dial in some tube warmth and use the parametric midrange modestly.

EQ: The graphic 5-band has its limitations. The range of each band is pretty narrow I think. For both the guitar and mike channels, I found the 12k frequency band virtually useless since there is no tweeter in this cabinet.

So for vocals, if you are using an SM-58 or equivalent workhorse, even pinning the 3.5k and 12k bands will not give you the crispness you are hoping to get from this essentially guitar amp. Still acceptable for small restaurant gigs but not PA quality. The 1k band should stay flat, it is very honky when boosted. The two lower bands could be boosted a bit for the lows, which seem to be no problem for this amp.

So I would try to use/test out a better mike that has a better high frequency response and see if it makes a difference in the high frequencies. BTW, you may want to invest in a simple level booster for the mic preamp stage as well. I used a 1/4" transformer into the same Tech 21 paradriver and it boosted the signal nicely and gave the appearance of a better high end response. Without a boost, I found that the level control at 5-7 was enough volume and it didn't break up.

Guitar sound of course will vary greatly. See above for suggestions.

The anti-feedback buttons for each channel didn't seem to have any effect- this applies both to high end squeal on the mike and midrange wolf tones on the guitar which really need a notch filter to level out. However, I found if you sang and played facing AWAY from the amp and somewhat to the side, both the mike feedback and wolf tones seemed to diminish significantly.

For an 8 inch speaker and small closed-back cabinet, I found the throw of the speaker to be direct but still with some spread to it. I wouldn't call the sound warm, but it's pretty clear. The lack of high end is less of an issue for guitar since most people go for a more natural, less clinky sound. Again, this is where your onboard guitar EQ or outboard EQ device can make a difference.

CONTROLS: Again, they are all delicate and I would very slow and careful when clicking between effects choices. As far as REVERB goes, setting #2 is a small-medium room which works well for the guitar but makes the voice sound boxy and mid-range dominant. I would go with reverb #3 for the voice (large hall) but use just a trace of it, like between 1-2. The other effects like delay seem to be just fine but that's not a need of mine. If it was, I would use an external multi-effects unit that has all those secondary effects.

Probably the biggest drawback/cutback on controls is the LACK OF A LINE OUT (phone jack and/or xlr).

If you want to patch this into a larger PA system, you're going to have to bring an extra mike for the amp. This could have easily been incorporated on the back mini-panel, alongside the CD stereo RCA ins and level control- a nice touch, especially if you are used to patching in your iPod during breaks. or those who use drum machines and other playalong tracks.

I will be using this on a trio gig tomorrow (with bass and drums in a small auditorium, no PA) to give this a real test. If it suffices for that then I'm sure I'll find a way to make it work for solo and duo gigs as an alternative to taking separate cabinet and head.

In summary, Behringer continues to make quality products for very reasonable cost- and this amp is certainly no exception. But it is far from ideal for the discerning musician who wants the best sound possible. If they read reviews on this site dating back over 5 years citing its shortcomings, maybe this could be a killer amp instead of an adequate one. I know at least the detachable power cable was one improvement they made.

The other issue, which is a marketing one, is that this amp is nowhere to be found in-store at GC or any other retail outlet. So you are basically flying blind when you order it. MF does have a great returns policy so if you don't think this amp will work for you, sending it back is not a hassle and you don't pay the return shipping.

This amp is good for practice and maybe even a small front porch gigs, but OMHO it seems like something high end I would buy at Target or Sears.The sound is good and clear, but the mic section had too much feed back (om2 from Audix).The speaker uses what we used to call a "whizzer" cone around the dust cap of the larger speaker cone. So the same voice coil is used for both highs and lows. The high end cant keep up with the lows at higher volume.I prefer a true coaxal speaker which look like the car speakers displayed at Walmart. Two seperate cones with the tweeter centered in front of the woofer, two seperate magnets, and separate voice coil.The effects sound generic and fabricated. At low volume, it sounds really sweet though, I'll give it that.Overall, sweetsounding, clear, crisp bedroom amp, great first amp for the kiddos!

Comments about Behringer Ultracoustic ACX450 Acoustic Guitar Amplifier:

could use a line out is my only beef with this amp
Just a follow up on this amp. I've owned it for three years now, and still can't get over the quality. I've played numerous shows, indoor and out and it just keeps on giving. If you're looking for a good sounding, sorta retro looking acoustic amp.....this is it. I tried out one of Marshal's acoustic amps a few weeks ago, and there was no comparison. The Behringer beats it hands down, and weighs about half as much.

Comments about Behringer Ultracoustic ACX450 Acoustic Guitar Amplifier:

Again, I would recommend this product. Very good sound & value.
I purchased the Ultracoustic ACX450 Acoustic Guitar amp from MF as I have been interested in this model. I received it yesterday, & after plugging it in (to make sure it worked) it was tested in combat at one of the weekly blues jams I play at. I played bottleneck on my regal resonator & '62 Grestch Clipper, & this amp kept up with other guitars, bass, drums, harp, & keyboards. Some told me I was not loud enough however I was not always playing at full volume. Amp is very clean with little distortion, although that is what I was looking for in an acoustic amp.
I played with it today with my '60 Gibson J45 w/EMG transducer, & a Taylor V-cable to control the volume at the guitar. I am very impressed with the sound of my Gibson though this amp. I have not had a chance to use the microphone channel, however, if it is anything like the guitar channel, then this is a great amp.
Good value, good product.
I was surprised about the front panel being attached with velcro as it is somewhat lose, however, now I notice that the front access is for the speaker, which makes good sense. I am still experimenting with the effects, however, everything sounded very good with my Gibson acoustic.

    Just a fine little amp. Good sound, nice features, plenty for your solo act. Mic channel has its own EQ. I used the amp for a 4 person jam session and it was great. Had to turn it up to 6+, but it is only 45 watts.
    I have a Beringer sound board so I knew this amp would be just as cool. Can't beat it for the price. I'm very happy with it.

      Excellently designed amp for smaller venues or home use. Can of course be miked for larger ones. The effects are very useful and easy. T ried a vew effects for acoustinc and they were overkill or dificult to figure out (like SZoom A3). This amp you don't need any exteral eefects--they are builting but engineered to enhace acoustic sound and not dramatically alter it. And there are dynamic controls for them. Foot swtich included is great benefit. Solid buy for money.

        Comments about Behringer Ultracoustic ACX450 Acoustic Guitar Amplifier:

        I perchased the Behringer Ultracoustic ACX450 Acoustic Guitar Amplifier on 9/12/13 and I am totally amazed with its performance. I am convinced that for the price I could not find anything that can match it. I've used it for practice as well as twice in a restaurant setting with other musicians. My Alvarez AD62SC acoustic guitar sounds awesome through it. I set the amp gain on five and the guitar on the same and found that I had more than enough power. I am still experimenting with the effects and have used the chorus, delay and reverb settings thus far. I have only use a microphone during practices to try it out. With the amp set on three and the guitar set on four with the microphone set on three, it held its own. Not only am I impressed, so are the musicians I play with. I was a skeptic even after reading all the positive reviews. I have never written a review before on anything I have purchased. I felt that this warranted me doing so. I would definitely recommend this amp to any musician looking for that bang for their buck.

        Comments about Behringer Ultracoustic ACX450 Acoustic Guitar Amplifier:

        Bass response is good. There is no tweeter on this amp so the sound is more bass to high mids. This renders one equalizer slider almost useless as there is no high frequency to boost. However, it does sound good enough to gig with. Surprisingly, you can play your electric guitar with it too, since there is no tweeter to blow. So low volume gigs where a small amp for electric and acoustic is possible with this. Since I bought this amp to sing and play out of in lieu of my bigger system, I'm going to install a tweeter. The volume of this amp is very good.
        Can't beat it for the price.

The feedback control is great. The effects are awesome. No matter the setting you choose, you can still feel the acoustic sound of your guitar. It seems to be built really well. Just wish it had a line-out.

        Comments about Behringer Ultracoustic ACX450 Acoustic Guitar Amplifier:

        I bought this Behringer ACX 450 about a month ago. In my opinion, this is a great amp for the money. unfortunately, l had to send it back. I needed a light amp and this said in the catalog that it weighed just over twenty (20) pounds. In fact it weighs over thirty (30) pounds. This is certainly is not a big deal unless you have some physical restriction and if I could have, I would have kept it The sound was great, the features were really good. You have a lot of control over your sound This of course is important with any amp but I think especially with an acoustic. I personally find it fairly difficult to balance the bass and treble and the Behringer did a super job. I returned it and got a lighter amp but I can't make it sound as good. If weight is not a problem, I highly recommend it.

        Behringer really missed the mark with this one. Don't buy it. It has good power and a good sound but it is cheaply made. The EQ sliders are made of thin pieces of tin. They break off with normal wear and tear from loading and unloading. Until they fix this issue I would not recommend this amp.

          After three years in...this amp has performed flawlessly. Played lots of shows with it, both indoor and out. It has always been my go-to amp for practice and performing. Now the sad part. Out of the blue I turned it on one snowy morning, and nothing happened. Pulled the fuse out and it was blown. Ordered new fuses and the same thing. I'm taking it to a repair shop to get a verdict. If it's relatively inexpensive to correct, I'll have it repaired. If not, I plan on replacing it with a new one. I bought the Fishman Mini-Box 60 watt, and like it, which sounds great and is pretty powerful in it's own right...but it's just not the same. The Fishman has far less diversity feature wise, but lots more umph to it. I love the diversity of the Behringer, and miss it sorely. Even with the problem I had out of this amp, I'd still highly recommend it. Just glad it didn't happen onstage.

              Played for almost 10 years now and this was the first acoustic amp i bought. Let's just say that this amp was well worth what I paid. I lead worship at church and this thing packs power. I barely have my master over 1 and it packs plenty of sound. The effects are nice as well and are easy to use. I also like the 2 channels so if i need to i can play and have a vocal mic plugged in. Again its great for small venues and has a nice warm tone. I play a Seagull Coastline Grand with a fishman pickup and it just sounds so good coupled with this amp. Great buy!

              Just bought this amp and to say I'm impressed would be a terrible understatement. The features of this amp at this price is unbelievable. True, clean sound with great control using the EQ and great choice of effects, true effects, that enhance the sound of any acoustic guitar, not just change it. You will not be dissappointed if you purchase this.

              I was looking for an affordable acoustic amp,one that was loud enough to be heard but small enough to handle & not take up too much space. This amp kicks.Great sound, loud, clear & good bass. Not too heavy either.I've had it for a month now & I play almost every day,I use it exclusively for my Martin dx12, Play a 12 string through this puppy & you'll see. It's well worth the money, I own other Behringer products, they definately can make a decent product for the money (as far as amps go)I bought this from musician's friend exclusively because of the ratings. Never tried it before buying it so I took my chances with the Behringer product & these reviews. "Good call" Not dissapointed. If your in the same boat I was, You should try it for yourself if you can find one.

              I played with one of these today at the local guitar shop; WOW! This is the first behringer amp I have tried and I was blown away. Worth every penny! I am going to buy the 900 to use with my DY40C Alvarez and old trusty S6+CW Seagull for an upcoming wedding gig.

              Comments about Behringer Ultracoustic ACX450 Acoustic Guitar Amplifier:

              I bought the Behringer ACX450 because I have several other Behringer products and I am amazed at the price vs features (in other words, value) of their equipment. I get a really good acoustic sound out of the amp, and when I tried my electric twelve-string I was really blown away (can anyone say VOX?). The effects really enhance the twelve string. But the mic section seems to be really underpowered. I don't know if the amp is defective or if this is the norm. But I use this for open mic night at a local pub and need the vocals to compliment the guitar. What I finally did was plug the mic into the instrument channel, and my guitar into the instrument channel. This seems to give a little bit better mic performance, the guitar is a little muddier (but still satisfactory). And of course the various XLR to 1/4" adapters (and vice versa) this requires complicates things a bit more. Bottom line - for just an acoustic guitar amp this is a great little unit with a very authentic acoustic sound. But for a typical singer/musician it leaves a bit to be desired. I may send it back and try another one and see if it acts the same. But overall, I'm happy with the amp, and definitely with the price.

              Comments about Behringer Ultracoustic ACX450 Acoustic Guitar Amplifier:

              This amp has really loud sound, good bass. From what I could tell, the sound was good. I could only crank up the volume halfway up, but that was loud enough for an apartment. Will try it in a larger setting sometime. The effects are ok. The Reverb is good, and the delay works, and causes an interesting sound. I haven't tried out the Microphone channel yet. One of the biggest reasons I chose this amp over the Peavey E208 was because this had individual Effects controller for each channel, so I can sing using Reverb on one channel and play the guitar through the other using some other effect if I want to. That is important to me. The Amp is heavy, nothing that will break your back but is not very easy to haul around just like that. It is quite a good looking amp. The wood-finished skin sits nicely on the front but on the back is not glued all that well. It is not really such a big deal that I should consider returning it, but I will try to superglue it myself. I would have preferred a metal grill at the front, but the cloth mesh is not that bad either. It kind of gives it a classic appeal. I have not tried to play around with the Feedback Detection system on this yet. Also, I have not tried to use a Microphone with it. Since this as an XLR input, I need to find something which will match. Ofcourse, you can also use a regular quarter inch jack for the Microphone input too. Just thought that the power cord could have been a little longer. For such a heavy Amp, I dont want to haul it around till I find a power point. Rather I would prefer if I can just sit it down and extend the power cord to a socket. BTW, it also comes with a foot pedal for effects, haven't really given it a try yet, but i can't foresee myself using that too much, but it is good to have i guess.

                I currently have a deluxe reverb 65 and the Berringer1000acx but they are heavy for my arthritic back. This amp is perfect, light weight,great sound from a 8" spkr. My gig buddies couldn't believe the great sound from instrument and mic. I haven't played a large room yet it's great in 30x50 so far. I have been playing several instruments for over 60 years and this amp sounds great with guitar and mandolin. I am very pleased!
