The DD-3 is by far the most popular digital delay box in all of pedal history. I'd go so far as to say its pristine delays have been repeated on more stages than any other echo device. This box is everything you'd expect from a hard-working digital delay unit. You'll get super clean repeats with no coloration, perfect decays, and enough delay times to create everything from short bathroom wall slapbacks to long cascading patterns. The same 3 "easy-as-pie" parameters you'll find on most Boss delays is here: delay time, feedback, and level. There is also a fourth "mode" knob that adjusts the delay time range and also switches the unit into "hold" (infinite repeat) mode for sampling snippets of solos or riffs. For an all-around delay box you can't really go wrong with the DD-3 unless, of course, your expecting it to sound like an analog delay.
