Make a pretty picture like that and make the shapers compressors and then I
have a Waves C4, the best little end-of-the-line compressor around. ;-)

Well, they would be preset for given amp types I guess.

For the record
my current guess for an amp process is:
.-> bandpass -> shaper -. .--- LP <--.
| | v |
input -> EQ? -+-> bandpass -> shaper -+-> delay -> EQ ---> output
| |
`-> bandpass -> shaper -'
well, we'd have to try it and see :)
the delay w/ lp in feedback - is that basically
how you make a resonant lopass filter? dont bother.
The EQ? could be optional if you have enough bandpasses.
Sure, if there is pre-shaper and post-shaper gain for each
band then that's your EQ. Lot of parameters to control,
though.
