Lives for gear
There's a lot of misinformation out there! Put it this way, 1100ms is a huge amount for a BBD, you don't find them that long for that cheap. There was a Moogerfooger one that was 1000 dollars or something.
Check this out:

In the comments:
" It´s two digital PT2399 chips, believe me or show me that I´m wrong... Even Biyang themselves? confirmed that, saying that "analog" only means that it sounds analog. I had a AD-8 and I had a look inside. And btw: I´m a pedal builder myself, I know what I´m talking about..."
Edit: And from that thread on GFS you linked!
"The Biyang AD-8 Analog Delay is digital, not analog. Just as AD-10 it uses PT2399 chip and not an analog BBD. The picture shown above is not from AD-8, actualy it is not from delay effect at all. The MN3007 BBD as mentioned is 1024 stage BBD, so to reach 1100ms delay of AD-8 you need like 16 of them, which would be insanity. The MN3007 is used primarly in chorus and flanger pedals, they are rather common and you can find them in Biyang CH-7. The costly ones are MN3005 (4096 stages) and MN3008 (2048 stages). In AD-8 case there are actualy 2 of PT2399, first one gives 600ms while the second is engaged for 1100ms mode, hence effect is marked as dual chip."
