I am using this amp for keyboard & voice mixing. It does the job well. I have a Yahama PSRGX 76 keyboard and it works great. I do not use the special effects built into the amp because, I have them on the keyboard. The 5 band equalizer gives exelent sound shaping and makes the vocals sound great. I think this would also make a great guitar amp because of the special effects that are built into the amp.

I'm comparing the UltratoneK450FX it to the similar 1800 model. I've used both for acoustic guitar and vocals. I was forced to use a lighter amp due to a bad back. The 450 is suprisingly loud. At least as loud as the 1800 although I don't get how this could be with the difference in wattage rating. I'm having to turn the 450 down at the same settings I hade with the 1800.

The 1800 has a much airier and crisper sound to my ear. The 1800 has a much more musical high-end and present upper-mids despite what you do with the EQ on the 450. It just sounds cheap compared to the 1800 which I've done at least 300 shows with.

The effects on either unit are very usable considering price. There are 4 imputs on the 1800 compared to 3 on the 450. The 1800 has 7 band EQ instead of 5. There are lots more options for connecting to other gear on the 1800. I hve not found the feedback control to be of use.

On the positive side, as I said, it is 16 pounds lighter, has suprising volume and has a hole for pole mounting which a feature painfully lacking in the 1800.If you tend to have a thin, trebly kind of vocal this amp may help thicken things up. In general however,if your back and wallet can take it, spend a few more dollars for the UltratoneK1800FX. I absolutely love that unit. I've had 2 of them.

            I have used this amp for 5 years now on and off keyboards only. Recently sold my cheep old guitar amp that use to use for practice and small gigs. Now using this amp. Sorry sold the guitar amp, the sound on this amp is very boomy around c3 keys. Have used this amp on 4 different keyboards the only ones that work well are the Nord electro and Korg sv1 with built in equalizers you can cut down the freqs in that area and make it usable. Now looking to replace the speaker to try and solve problem. If your going to use this strictly for a keyboard amp pass on it. Oh by the way the effects quit couple of years ago.

              Never have one shipped thru the US Mail. The shipping container looked like they had dragged it all the way to my town. The amp wansn't visably harmed but I can't tell about the insides and all of the evident jarring that it must have taken in order to destroy the box that it was shipped in. Ask to have it shipped vis UPS or FEDX.

                Plays like I'm in a club, shakes the floor, boosts sound out of my Casio keyboard and when I just want to chill and listen to my YouTube playlist from my iPhone it sounds great.

                Comments about Behringer ULTRATONE K450FX Keyboard Amp/PA System:

                Really like this amp. I use the balanced input for a mic and the 1/4" for my guitar. I have a output control on my Ibaneze so can balance the 2 together. That leaves me 2 inputs for other instruments. I had problems with other amps not having enough "PUNCH" and had extra hookup with an external mixer. I use the "KISS" technique. "keep it simple stupid". It really simplified my setup. Also liked the balanced input for mic as it gave me more output from my old Electrovoice Mic.

                        Bought this for almost 6yrs already, basically as. A keyboard amp. This thing experienced snow, slight rain almost all kind of weather here in alberta as i have to walk and carry this thing to our practice venue. And never had a major issue with this thing, and really pleased with it. So i decided to give this thing a good review wich is overdue already. as BEHRINGER definitely deserves it. That's one of the best thing about behringer great quality and very affordable. Just compare the price when you shop around plus the features and other people's review.

                        K450fx has 3 channels with dedicated send fx for each + 5band eq, + 100effects + cd in. Etc. great package! I even use it for my electric acoustic guitar. And sounds really good. I was thinking of buying a fishman but it seems that k450fx will do the job.

                        The only con i can think is that it seems to be not powerful enough to handle 3chan els when volumes are cranked up

                        Overall it is highy recommended

                        The amp arrived quicker than I anticpated; it was well packaged and a joy to see. Very compact, but packs an awesome punch! I have it for my digital piano and it provides for great pick up in the open space I have positioned them in.
