are the danelectro fab pedals digital or do they actually have components (pots, resistors, transitors)
I believe they are not digital (with chips) but I could be wrong, wanna know to mod/dissect effects units

They're analog, I looked it up. Might be a fun project.

They're analog, but you don't want to use them to experiment since most of their components are surface mount, and thus a real pain in the ass to work with, certainly not something to learn modding on.
I haven't tried modding but my guess is that the easiest thing to start with is DIY clones, especially fuzz boxes/ODs since they're comparatively easy to make.
A friend was going to pull apart one (the chorus) and see if he could build a better chassis for it. Although I have (temporarily?) retired it from use.
It's an opinion. It's subjective. And I'm right, anyway.
