Getting Started (AKA What is the best...?) • Re: Frequency modulating a comb filter

So here I am frequency modulating a comb filter, in Largo. And I am wondering - what is the FM doing to the comb, since a comb filter is a short delay, where Cutoff is delay length and Resonance - feedback depth.

For more clarity, the manual says:
The Comb filter types differ from the other filter types greatly, because they don’t actually damp any part of the signal, but instead add a delayed version of the input signal to the output.
:help:
While it is true that a 0 dB gain, delayed signal in isolation doesn't contain amplitude modifications of the original signal, the adding of a delayed signal on top of the original signal does cause modifications of the amplitudes of the frequency components, reinforcing some and diminishing others - not just producing resonances. That's how IIR (aka recursive) filters do their work.
