Behringer Ultracoustic ACX450 Acoustic Guitar Amplifier  

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.

could use a line out is my only beef with this amp

Can't beat it for the price.

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.

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.

Again, I would recommend this product.  Very good sound & value.

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.
