i do think that the in-cab echo is part of the impulse response
if you have a convolver ('imp_1199', 'unmatched') following the
shaper summation node. it sounds to me like it is fwiw. how many split bands do you think we'll need?
My guess is one for every two octaves. But that is absolutly a guess.
What is the frequency range of a guitar amp? If its more than 8 octaves it
might be neccesary to widen the bandpasses past two octaves, or maybe the
top end can just be lightly shaped together.
Who'd think one small wooden box could be so complicated ;)
