Behringer’s ACX450 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 5-band graphic EQ for tone shaping. On top of that, each EQ features FBQ feedback indication to help you terminate feedback quickly.
FBQ Feedback Indicators:
Engage the FBQ control on the ACX450, 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.
Behringer’s ACX450 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
