DD-2
The first compact digital delay: repeats that keep their treble.
What the circuit does
The signal is sampled, stored as numbers and played back unchanged. Nothing in the storage path removes high end, so the tenth repeat carries the same frequency content as the first, which is the exact opposite of what a bucket-brigade line does.
What to listen for
Repeats that stay bright and stay present, right up until they run out of level. That clarity is a virtue for rhythmic parts and a liability under a busy mix, which is the whole reason people keep an analog delay as well.
Where it goes
The delay slot
Near the end, repeating a signal that is already finished. Anything placed after a delay processes each repeat again, which is occasionally the point and usually a mess.
