I keep trying them, because I know I'm supposed to like them, but I just don't. At all. People say they are more natural. Warmer. I think if by warmer they mean "under a blanket", I agree. I don't think they sound natural at all. If they're meant to mimic old lo-fi technology, they do that well. To me they don't sound anything approaching "natural". To me, they sound like a man made fake echo developed before the tech existed to make a clean sounding echo. I'm not slamming people who like them. If that's the sound one is after, coolio. I've just come to find that with every one of these I try, the sound I'm after just doesn't exist in the analog delay world. I want clean repeats that sound like the note I just played. Like a real echo. Real echos have clean repeats, that gradually drop off in volume. But they don't distort, sound muffled, or wiggle around. Old machines do that. Alright. Rant over. Move along. Nothing to see here.
