This is the pinnacle of reverb pedals to me. It really can be as big of a cavernous delay as you make it. As the description says it really uses a series of short delays to reverb. The DRAG knob is the absolute coolest feature about this pedal. The knob gives you the option to speed up or slow down the delay to get the perfect reverb. This is an ambient noise lovers' dream. You have to pick this thing up.
