I can write up an explanation for you tomorrow if you’d like, but be warned— it requires a dual expression pedal and two expression jacks, which there isn’t room for in a normal build; you’d need to build it in a bigger enclosure, like a 1590XX, which might not be appealing to you. If that isn’t up your alley, you might prefer building the madbean harbinger two, which is built into a Wah shell, but isn’t exactly the same as the Electrovibe.
