It reminds plate reverbs. Very simple one. I don't think it is useful for making a space for a mix. More for individual channels to add tail or fatness. And also a cool thing - it works in stereo. So it you pan then it will sound in that pan position. I think dumping sound unnatural so be careful and consider what you want. Better to use low pass. Or the bandpass is also works well. Or use additional EQ on reverb channel.
