Your basing your pont off of the fact that you bought two pedals from China with the same chip, but are labled as "digital" and analog". That seems about shortsighted.

For example, the description of the Mad Professor Deep Blue states:

"The Mad Professor Deep Blue Delay is a natural sounding digital/analog delay, with analog direct signal path."

Skreddy Echo:

"Ultra-High Sample-Rate (Delta-Sigma) Digital Delay with Analog Filtering and Limiting...Transparent, Analog "Dry" Path with Tons of Headroom"

Wampler Faux Echo:

"With our hybrid design (completely pure analog dry path with the digital delay layered on top) approach, you get the best of both worlds. You get the note clarity, much lower noise, and longer delay times from digital delays... You also get the lovely warmth and little exquisite touches that are usually reserved for analog delays. Nearly every part of the pedal, all of its major functions, are analog. The “delay line” is the only digital part of the signal path. It alone being digital brings clarity and focus to the task in a way that analog delay line chips can’t really match."

Those all seem like pretty accurate descriptions to me, and they aren't oversimplified.
