There's really something special about the clean and punchy repeats of the DD5, I will never sell that one.I use the Boss DD-5, and it is terrific. 11 different modes (possibly overkill), and the delay sounds on bass are tremendous. They're discontinued, but can be easily found for not a lot of $s. Best delay pedal I've owned, and I've owned a ton (pedal junkie).
I also have a Strymon Timeline : Excellent delay that covers everything and better sound quality than the DD20 I had. The DD20 gets the job done for basic delays, 4 presets, not pricey and in a live setting I doubt I could hear the difference between it and the Strymon.
