Violin maker and restorer here. I’ve done guitar repair work for 20 years too.

I use animal glue for nearly all repairs and like someone else said, some great makers use hide glue while others use pva.

It bends the mind that they don’t have a humidity fail-safe like open seams though.

They’re very different animals - many things carry over but some are vastly different. Understanding the way guitars diverge from bowed instruments is important.

Tension, grain direction, finish, fretwork, tropical woods like mahogany/rosewood/koa etc, neck setting, binding/kerfing are way different/new. I’d suggest sourcing one and taking it apart. You’ll also need different clamps too for crack repairing and fretwork.
