This is a Behringer BXR-1800. I mainly used it with headphones. I think it's a simple and easy-to-use head amp. You can distort the sound by increasing the gain, and the equalizer allows you to adjust the sound from scooped to mid-heavy. It has a simple +α feel, with features like Ultra Bass boost and compression. The graphic EQ's light intensity is unstable and sometimes turns off, but it doesn't affect the performance, and it can be fixed by adjusting the graphic EQ. Please understand that this is a used item.
