Two Channels:

Behringer's ACX900 is a true dual-channel stereo amplifier. Channel One is for your acoustic guitar, while Channel Two gives you inputs for either a microphone or a line-level source. Both channels feature a 9-band graphic EQ for tone shaping. On top of that, each EQ features FBQ feedback indication to help you terminate feedback quickly.

Engage the FBQ control on the ACX900, and LED's on the graphic EQ come to life. The LED's fluctuate in intensity, in response to the input signal. If feedback occurs, just pull down the fader that is glowing brightest - you'll wrangle in that feedback in a flash.

Built-in FX:

Behringer's ACX900 gives you two separate digital FX processors, one for each channel. Each has 16 presets including reverb, chorus, delay, and more. You can even tailor the chosen effect to your style with the Parameter dial.

Excellent sound from my new Behringer amp!!

Could not be happier with my purchase. The Behringer amp makes my Martin sound great!!
Music background: Have been playing guitar over 30 years.

Behringer ACX 900 90 watt Acoustic Combo

I went into the rock shop to get a fender amp for my Martin Acoustic Guitar. After testing various models I selected the Behringer ACX 900 90 Watt Amp which has turned out to be a great choice of amp for my acoustic Martin DM Dreadnaught. It has put a great new angle on the sound of my instrument and think Behringer has done a great service for acoustic guitars
Music background: Student

Many better options

I have owned one of these for eight years and used it only sporadically because the sound quality just is not there. I play through a small mixer board into a powered Pa speaker as my acoustic amp and it blows this thing out of the water. The only good thing I can say about it is that after all these years it still works. The only people who would think these sound good have never heard anything better.
Music background: Been playing in bands and as a singer songwriter for 40+ years.
