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

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

    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.
