I think I even have it... but as far as I know it's not capable of doing anything non-linear, right? The processor I used is highly non-linear.
My thoughts exactly, as I have the plugin as a sort of a sleeper in my plugin folder as well. Before I made the guess, I checked and it does indeed have separate stages for distorting the signal and the like, and even a couple of guitar speaker presets as a proof of concept. Definitely not its main use, more of a curiosity. Quickly tried to recreate the sort of sounds you have going on there, including the modulation
, and got "sort of close but eh but dang I'm still gonna guess this one."
Trying to figure out something surprising and out of the box here
