My answer to any "maybe glue back together" question is some homemade kintsugi hack. Sand the outer edges of both pieces to widen the "surface groove", mix some gold-ish/silver-ish/copper-ish/etc powder with some resin adhesive, glue.
Long time guitar owner here. You could get some wood glue and use a small amount to affix the chip back to the guitar pretty seamlessly so long as you've got a steady hand. In my experience it's harder than it looks.
My direct advice? Keep the missing chunk in a safe place and live with the guitar as-is for a month. There's no rush and this will give you some time to process.
If the gouge ends up sticking in your mind as something you want gone? Call a local luthier, explain what happened, that you'd like it restored, and ask for an estimate or evaluation if you want to budget for the expense. If you have a preference for a kind of repair you can ask for that too. Mending a wound on an instrument can be an opportunity to add beauty instead of simply removing a blemish. What kind of repair you want is entirely up to you and a temp fix now might make the repair more difficult / expensive.
If none of that sounds appealing and if after a few weeks the idea of a nail polish scar or other punky hack makes you happy then go for it! It's your instrument and best is conditional so go nuts. 🙂
My only concern with leaving the natural wood exposed would be moisture and cracking/paint flaking over time. Even if you think the chip looks bad ass and you end up wanting to keep it: I would ask a luthier to seal it up to preserve the instrument (battle-scar and all).
chips and dings definitely add character, but if you’re sore about it I’m sure a guitar tech can repair it nicely, or at least guide you to someone who can
Its a dark finish, marker would definitely make it pretty much invisible. the wood is white underneath making it very noticeable. Wife has some black nail polish :)
Marker will look good for now, but in a couple of weeks it will probably be fairly noticeable again if you're doing it straight on wood.
If you want it to look good. Sand down the area inside and directly around the chip so that it's smooth. Brush on a layer of white primer, let it dry for a day, then layer on some paint in whatever color and finish of the guitar. Maybe some sealer if you want but if it's just a chip I don't think it's necessary.
It sounds like a lot of work but it's maybe an hour or two of actually doing anything, and for a thousand dollar guitar I'd say it's worth it. I like projects like this, though, maybe you're ok with the slightly faded Sharpie. I would still smooth the area out with some light sanding first, though.
If it is brand new I don't think I'm going out on a limb to say you likely purchased it on a credit card.
Many people don't realize that a 'standard' credit card feature is 30-90 day lost/damage/stolen protection. So I would look up your credit card policy and see if it's there and if you could take advantage of that.
edit: oops wrote year not day lol. Also might as well add in that I've used various "cardholder benefits" before. Like the +1 year on warranty, which I used on a Costco laptop once. Costco doubled the 1 year mfg warranty to 2 years, and by buying on my CC I ended up with 3 in total. When the motherboard died 2.5 years in I got a full replacement which obviously ended up being from the newest line and better than what I had!
If you spent that much, but are hesitant about getting work done on it, try watching this guy. Sometimes it helps getting a look at the repair business. https://m.youtube.com/watch?v=ids3_Kxmi_I (this is just a random video, but he has some with refinishing) Or let it keep the ding, the first one is always the hardest with these things, but you got it to play, not the look nice. Accept life and its imperfections
