Interactive Frequency Response of popular pedals - update

I made an update to the graphs, the one remark i'd get the most was to get one curve for all knobs, so here it is, I am halfway through and hoping the existing ones will be finished by the end of the week.

Keep em suggestions coming, what else could I do to improve these? any idea?

here is an example for the legendary Bad Monkey:

I can do this using a Bode plot from the SDG->pedal->SDS then take screenshots onto USB then use shortcuts to combine screenshot into a GIF - very manual and involved. The bode plot takes time for each run and there's multiple runs for changes in the knob positions.
Better option for me is simply do a min, mid and max, with a shot, that would be enough permutations to pass hours..

Only issue is that for things like fuzz or pedals that add or modify sound, the frequency will need to be quite wide.

Not sure i fully understand what you mean, maybe you could show us what you've done?
 
This is a bode plot for a tube screamer mini:

This is with a 1Vpp input. Tone and Level at 12 oclock, distortion at 3oclock. A bode plot shows the frequency response difference between input and output.

One point in measuring like this (and modelling the pedal in a gif) is it assumes that the pedal will respond the same with variation of input Vpp and of impedance (fuzz pedals).
 
Thanks for sharing this! I still don't get it to be honest. Are you asking me what it is I have done or are you offering to adjust mine?

Have a look at this one for example and tweak the knobs: TS 808
