My use case for this is to add a little room type slapback delay. It does this very well.
For the sake of clarity, I am not particularly experienced with delays.
I set repeat as low as possible, level at about 11 o'clock and delay anywhere from 10 to 12 o'clock. This on it's own, provides a small room effect. In conjunction with my reverb pedal, it adds vintagey-deliciousness.
Highly recommended for this use case.
