This is a fully functional DBX 160x compressor in fair used condition. Everything about the compressor works, it's just kind of ugly on the top and the bottom with all the scratches. The blue knob's cap is also a little bit off the line of the knob setting, but it gives a general idea. It might just need to be put back on correctly, but I didn't want to mess with it. The blue knob also does seem to turn a little easier than the other two. The knobs in general don't feel smooth and solid and stable, but they do function and the compressor does work like it should.

The compressor sounds amazing. I will also say that this unit runs quiet. I've owned some of these in the past that buzzed like crazy when powered on unless you applied weight to the top of them, but this one is very quiet and nice in that regard. 

If you have any questions, feel free to ask, thank you.
