Are you looking for an application circuit? There's one here:

General Guitar Gadgets has a kit, the web site has a schematic.

No, I'm interesting in schematic of circuit inside BTDR-1 module.

Me too !!!
Aren't we all?
But I think it must be a State Secret.
Besides that, I'm *sure* it's a custom built OEM IC, with everything burnt on unreadable ROM.
Anything else would be a commercial suicide.
I think the second best option is to read a lot about DSP and Reverb algorithms.
A colleague in Brazil is making an incredible reverb pedal, in a joint effort with others.
Somebody else (I think it's a British guy) programs his chips and sends him monthly upgrades.
Just check:
YouTube - Alien Space-O-Verb
I think that's the way to go.
PS: I think it's *better* than the Belton one.

No secret...

there're three pieces of PT2399 with different delay times, feedback and signal levels / mixing, one delay line with modulation inside Belton module. It's based on Neunaber patent.

Interesting info.
Where did you get that from?
