MXR Carbon Copy analog delay - it's a delay and it's a nice shade of green.

...and I can't think of anything else to say about it. I've owned this pedal a couple of times and still can't get inspired. It's not a bad pedal at all, the real flaw being the lack of 100% wet delay and the modulation isn't very controllable, but it sounds alright. It just doesn't tickle the sensitive areas of my brain.
