Greer stuff is gorgeous, it's all made by hand to order in Georgia USA. The Black Tiger is their first delay, and they've voiced it on a combo of a couple of studio tape delays and an oil can style delay. It's clear and warm, with that little bit of texture and grit forming as the repeats taper out. It's great for more gnarly self-oscillation stuff too, if you're into such pursuits.
