Thanks for the info! Did some reading and I can see plain reverb being time invariant indeed :) I never realised chorus pedals did more than just stack frequency offsets onto your signal, but I only really play distorted so choruses are of limited use to me.

Pasting the other response below as well:

> Ah righto, the reverb pedal I'm most familiar with turns out to not be just reverb - EQD Afterneath does a whole bunch of funky stuff. Plain reverb though, yeah. I was approaching this more from the angle of training a neural network, where the input and output waves have to be correlated over a great span of time/ samples.
