I just ordered my first electric guitar

Now we're getting into filing nuts.

Did you dare do the test?

That is the final step to as perfect as equal temperament goes.
- so lovely when intonation is there anywhere on fretboard
- all fretted notes, or mix fretted and open etc

When all else is setup and done with. Just do the test.
- but fret usuall pressure, you can get sharp as you want to

This was general tip to anybody, not only OP for his guitar.
- I wish I figured that out much earlier in life with shitty intonation
- saddles and 12th perfect and yet not intonating

As I refretted a hollowbody I felt I almost emptied Stewmac warehouse on stuff, so got these files too. But a guitarshop should have a guy that knows how to.

Saddle height, intonation and the truss rod.

I might add nut slots height, as well. Check with a 0.1 cent tuner if fretting first fret is anything off at all.
- that might be a job at a shop if not having slot files

Besides requiring specialized files, it's also not easily reversible if you file too much.

True, do you think I've been there?
- sure have

Sanding off a bone nut for some material and superglue, works pretty well. Best to fill slot and then file down again.

To reassure the OP, it's highly unlikely that a PRS will have a poor quality nut - even the SE version. I bought an SE-24 myself a few years ago and it played nicely right out of the box, and so did the other 3 or 4 that I tried out while I decided on a colour. I got a free setup thrown in so the shop's resident tech restrung it with 10s instead of the factory-fitted 9s, and tweaked the setup to suit. Nothing I couldn't do myself, but it was free so...

Anyway it still plays nicely and it's very low maintenance. I think it's only the second brand-new guitar I ever bought, and I've never considered trading it in. And I've traded a ton of guitars over 50years so that's saying something. Enjoy your new plank

My post about Indonesia‘s humidity levels being the same as the US was sarcasm. When I go to Thailand to train Muay Thai, I sweat more than Arizona’s entire annual precipitation.

In all fairness, that's mostly due to the curry.

[Uncle E]

That's true. Arizona is famous for their curry.

To reassure the OP, it's highly unlikely that a PRS will have a poor quality nut - even the SE version.

If referring to nut slots, it's just that slot heights are not optimized from factory.
- not that nut is bad quality

It's the very last thing you might do, once strings guage and action are decided.
- so better that too high from factory, and create sharp note on fret 1.
- just file down as needed

I bought a neck for a Tele from Fender, and explicitly said slots are rough cut.

I've seen YT vids from experienced luthiers that go by mm so and so over first fret.
- I'd say that is rough
- final test is when guitar is set up and with a tuner
- fractions of a mm makes a difference

Just for those that feel guitar too often does not intonate well in certain situations.
- 10+ years ago tuners with 0.1 cent accuracy were not that common
- easy to check what status is

When guitar is fully tuned, ever did low E 3rd fret and hit open G, and not on pitch?
- do that interval up the neck too

Such a bliss when all is clean sounding.
