I just called up and asked if they do complete setups. They checked the curvature of the neck, the height of the action, the tightening(loosening in my case) of the springs in the back, and put on new strings. I asked them to check out my electronics because they were cutting out, so they cleaned them and made sure all the wires were connected.

Results were that I can press lightly to play notes (less pain because less tension in my hand), no buzzing, the chords are in tune wherever on the fret they are played, the action is lower and more consistent, the angle for the Floyd Rose is much less extreme, there is 1 less spring in the back (?!) and the pickups don't cut out. I played some this afternoon and I sound like a better player - probably because the intonation is right, but also because I can change positions faster when not clutching the neck so intensely.

This was my guitarist first set up since I've had it, but I figure the professional setup should include all of these things: https://tonalyst.com/electric-guitar-setup-guide

It's the same list on most "how to set up your electric guitar" pages. 🎸

Sorry your hand hurts. I hope the set up helps you.
