I think that is basically what the crossfader is a DJ mixer is - a

need any pull down resistors or anything of the sort.

I suppose that it is the way it was done in pro equipment for decades
might ease your mind. The modern way is digital, but that has a
higher startup cost.

Yeah, that would ease my mind. And digital is definitely out of the
question. I just do this recreationally and digital might be a little
over my head right now. Not to mention that I'm just building a
single unit right now. This isn't a prototype for something that will
be mass produced or anything.

This is going to be a piece of guitar equipment anyway and the guitar
community is a funny group when it comes to tubes vs solid state vs
digital. Concerns over digital sampling rate and resolution make
sense but still...

How would you compare the difficulty of developing a digital circuit
to developing an analog one? Is it any more difficult or is it just
more to learn?

At your current level, analog is fine. There was plenty of studio and
broadcast equipment built that way. Hunt around you may be able to
find some really cheap (near the level of haul it away and it is
legally yours). Decent digital is getting much cheaper though. It
mostly leverages your home PC for compute power. You might look at
RME and similar that you can find on any search engine.
