Seam in Bookmatched Tops?

Postby SilkyHotLicks » Sat Jul 21, 2018 8:18 am

I recently purchased a GIS guitar that was "No Return, No 10 day Trial, No Refund". It has a slight 1 1/2" (3cm) long bump behind the tremolo bridge where the bookmatched top meets. I can see it (if I look very closely) and I can feel it when I rub my finger over it. Is this going to be a problem over time?

beautiful

under the gloss i suspect you are fine

this problem you have identified goes in the list of:
*selling cracked tops
*filling in cracks, and selling them that way instead
*reorganizing with a worker doing nothing but QC at the end of the line
and so forth

Okay, thanks. Perhaps this explains why there are so many "No Return" guitars in GIS these days.

My CS6 from 10 years, 4 months, and 19 days ago with a flamed maple top has this. When the guitar was delivered it was mirror-smooth, but over the years, if you tilt it and catch the light, you can see the pattern of the flamed maple underneath rippling slightly in the clearcoat...and with that, there's a very slight raised area in the middle where the two top halves come together, because there is a glue line here, and glue doesn't shrink/move.

But I don't say that to throw Carvin/Kiesel under the bus as some sort of manufacturing defect or flaw.

My black Gibson les Paul studio had the same line along the center body seam. It was VERY pronounced. It was more visible in the back, too, and the hilarious part was that it wasn't actually exactly centered. It was a dead-straight line, but it was slightly off as it passed under the TOM bridge, and then missed the bottom strap button (which was centered) by about 1/8-1/4" :laughhard: Oh, Gibson.

My $4K Taylor is juuuuust starting to show this center line too, if I turn it just right and catch the glare right on it. I can't feel it yet, but I can see it and it wasn't there when it was new.

In a thread over on TGP, here are some quotes in response to someone asking a similar question about the wood still seemingly moving under the finish:

I have the same thing in my Hamer Studio Custom and PRS DGT. Had Suhr in the past with it as well.

With highly figured wood it's going to happen as the wood shrinks and expands under weather conditions. Sanding sealers are really not used for catalyzed finishes. Undercoat is usually polyester. But even when thick it will usually reflect a figured top eventually.

I have a Tom Anderson Hollow Cobra S that has a distinct rippling in the mirror finish on the flamed maple top. Makes it very obvious that it's not a 'photo flame' as the rippling follows the visual grain of the wood underneath. It didn't start out that way, but once it had been exposed to a hot summer the wood lost its perfect mirror flatness and the cured poly finish being thin followed the rippled grain pattern. You can only tell from certain angles in the right light, but I like it.

Yep, that seems to be exactly what happened with my guitar-- wasn't even super warm for it to start the process.

Like you said, it's a nice reminder that it's a real flame top and not a photo flame. And a reminder that these things are made of wood! Something that's easy to forget on super shiny, sometimes thick (but not in this case!) poly finishes.

Had this happen on a couple of my Ibanez J Customs of the past. No issues or problems.


Here are two photos of someone's $3K+ Tom Anderson semi-hollow Cobra S with a similar issue. They said:
BTW, that guitar is nearly 9 years old and has been like that for the last 8 1/2.

Wow, I don't understand this, I just counted the number "No Return" guitars and it's 28 of 63, that's 44% of the guitars in GIS are not eligible to be returned. And my new GIS guitar, while very beautiful and unique has a total of three minor finish flaws and is also not eligible to be returned.

All of this beauty and flaws for $3,288.97. And I still have a ZA7 and VB6 in the oven.

The first two *seem* like perhaps polishing compound, from the guitar being cleaned/detailed before being shipped (since it was at least at the store and possibly also NAMM), and some just got into the grain of the tung-oiled neck (is it a tung oiled neck?) :think:

The guitar feels, plays and sounds wickedly good, so I'm not going to make any more waves about it. I was just more so worried about the bump in the seam. And yes, I saw it at NAMM, picked it up, noodled around with it for about 30 seconds and put it back. That's all it took for me to know that I would buy it if I saw it in GIS. 8)
