This amp is a 10, nothing less.

Got mine today, and setting it up took me a just a few minutes. Using a Shure SM58 for vocals and acoustic harmonica works fantastic with the ACX450. My amp family is all tube amps from Vox and Ampeg. So this as my first experience with this Ultracoustic ACX450 is being truly overwhelming, so to say. I expected much less for this low-end price and being rewarded by such a high quality product is great indeed. Sure, I could have spent a 4 digit amount but I kept to my budget and for this Behringer amp the price-to-value ratio is unbeaten, at least to my knowledge. Crisp, clean sound, reverb 3 and 4 sound organic and the looks of the amp are eye-catching. Zero feedback, even when I dialed in a 9 on the GAIN. The modulation and delay section is another option which actually does not fit too well with my voice and harmonica tunes. However, I instantly decided to skip all this modulation which is no problem at all for my performance as a singer/acoustic harp player. I will figure if it makes sense to use this modulation/delay on board effects when plugging in other instruments. For now, everything works out at its best. I will use this amp for rehearsals in my studio and on smaller stages. Last but not least, Sweetwater Music and their sales engineer Phil Potts provided a top notch service, like always. Thanks guys, the world of acoustic music starts to shine!

Tube like tone!

I have owned this amplifier for over a year now and continue to be amazed at the wonderful tones. The 8 inch speaker has wonderful voicing. Now only does this sound great with acoustic guitars, but try a hollow body or semi-hollow body through it. My Casino Coupe truly sounds like it is plugged into a tube amp through this amplifier. I also use vocals on this amp. You can tweek your voice with the controls and get fairly loud and good vocals . I hate to admit it, but the clean tone on this amp sounds much better than my Line 6 Spider Jam using an electric guitar, and that Spider Jam has to be among the best modeling amps. How does Behringer do such quality for such low prices? Been playing for 40 years. Go try one and see what you think.

Great Fiddle and Vocal Amp

Had this amp since 08/2011. Plug in my Realist acoustic /electric violin and Shure microphone and let it rip! I built a small plywood wedge (Nashville style) to set the amp on. For bar gigs, wedding parties, etc I tip it towards me and it fills the room.Put it behind me if I need more volume for larger spaces. The instrument EQ sliders set the violin sound I want, and I add in a little reverb. I've been gigging out for 30+ years and this is a perfect rig for me. I sing and my accompanist is either an un-amped electric piano or acoustic guitar thru' an old Laney acoustic amp. This amplifier is still very quiet (no hum) and has traveled all over Maine in the back of my jeep. Fiddle goes directly into amp, no need for stomp boxes or separate EQ. Pretty simple set up: amp, wedge, mic stand, cables = one trip in and out of the venue! Bottom line, this amp makes your violin sound exactly like a violin, is simple and ideal for my use.

Great little amp!

Great little amp for any singer songwriter for small venues and practice . I'm totally impressed and have had mine for 8 years now . Good effects foot switch even an aux input for break music . I use it when I don't need the power and performance of my Marshal AS100D soloist system which in my opinion is the gold standard for an acoustic combo amp. For the money this little behringer can't be beat !

Great value and great sound

The sound is incredible for and amp in this price range, good array of effects, and yes it come with foot switch to turn effects on and off. Play my Martin acoustic electric and my Washburn acoustic electric through it and they both sound great (real natural sound). I also use it for my vocals and get a great mix with the eq and the effects. Well worth the purchase price\.
