Re: NGD! MXR Carbon Copy!
Well, I'm not so concerned with the technology inside as how the pedal sounds. Radical concept, I know. So, yes, I would lump the Bell Epoche in with the CC, because they because they're both older-school, lo-fi sounds with modulation and/or wow and flutter. Obviously, the tape-emulating BE takes it to farther extremes.
On the other side I would put the digital delays that don't pretend to be analog; DD-3, other DD-'s in digital mode, Flashback in 2290 mode, etc...
Actually, in my case, this is a second delay on the board for "other" sounds. My #1 is a DD-3. Sound is secondary, though having a voice other than the DD is a nice-to-have. My primary concern was that the pedal HAD to be MXR-sized, because of it's location on my board. The CC gets a lot of props, and I found one for a price that gets around my main complaint which is that the CC seems too expensive for what it is. Problem solved.
