NGD: Southern Jumbo Original 2023 and possible issue

[Saberslash]

 

Hello, I got myself nice southern jumbo, brand new, but yesterday I saw this line...could this be a crack in a side of a new guitar ? 😞 😞
When I check inside, I do not see any crack and split(when I look in a hole), only on the lacquer side outside.

 

 

any experiences? tnx

I’ve had that issue on new guitars recently.  I kicked up the humidity settings in my guitar room and they went away. In my case I was keeping the room at 40/45. Now I keep it at 45/50. After a couple years, they’re not as temperamental

Is this lacquer checking or wood split / crack? thanks

Just look inside the guitar and it will tell you the story.  But as Dave F. says they will settle in after a while.  As has been said it takes a guitar a bit to figure out it is no longer a tree.

Inside all looks solid. So it can't be that outer layer cracked and inside is fine? 🙂

If you want to confirm it is not a crack that goes all the way through, you can soak the area down with Naphtha and look for seepage inside the guitar.  Doesn't look particularly worrisome to me though.  And congrats on the new SJ, a fine guitar.

In my case, it’s a newer 1942 SJ with the cooked top. It was just the lacquer and after I turned the humidity it disappeared. 
I did the same as you as far as looking inside.

I had a similar line on a J45. It was the lacquer, seemed to follow a line in the grain. I have had the guitar for several years and you still can just barely see it but it has not been any sort of problem and was certainly not a crack in the wood.

Do you have any images, I am really curious ☺️

There is also a video of that same finish line I have uploaded

Here's what I have on my SJ. It was more open but it's better since I upped the humidity

Around the same time, I had the same issue with a Jackson Browne

Can you feel that under your fingernail or finger? or is it underneath the clearcoat? Mine can't be felt at all, it is all shiny and glossy and flush.

It has pretty much gone away.you have to hold the guitar close to a light and angle it just right to find anything now.

Have you decoded the serial #, or maybe the final inspection checklist date so see just exactly how fresh this guitar is? Also- it would be good to know relative humidity. Or, if you were in the southwestern US. Or high altitude.

You should be ok with that- just watch humidity levels for a while, esp. with such a new lacquer finish. You can have a look inside the guitar with a UV light/lamp. . . it'll give you some information. . . maybe too much information. ;  ).

I can only feel it at one spot where the wood meets the binding.

Yes, it is made on 7th June 2023, guitar is now resting and being played in a room where relative humidity is 50% 🙂

Those are starting to show there vintage appeal.     
I would say about 50% of what New Gibson acoustics I have are the same little issues.

I agree. When I pick up this guitar and play it, it looks, feels and sounds like something out of the early 50's
