I've used 1/4" plates in box ends (knotched for neck and drilled for output jack) or quarter-round in the corners of boxes that I thought might be weak.... however for neck thru, with undamaged boxes, I don't feel the need.

the best,

A bead of glue in the corners and along seams may be over-kill.....but, its cheap over-kill. I do it to all mine, for what its worth.

I also run a bead of wood glue along all seams on my neck-throughs. I add small braces to the corners of my non neck-throughs.

I always glue corners and seams,remove all stickers and felt from the inside first. If the box is gonna take a beating ,or have a real heavy neck I add bracing but never anything major.

Mostly as a sales tool I too re enforce the sides and corners of most of my boxes.I tend to just rip down some scrap left over from building the neck and glue a piece in each corner and then run a bead of glue along each seam all the way around the box.It makes me feel better knowing that the box is stronger then it was when I got it.
Does it kill a bit of the sound? maybe, but I think its offset by the knowledge that the box is stronger.

I havnt put any glue inside any box that didnt need it. I am a professional carpenter and use titebond 2 on everything that needs it. It still wont stain so be careful. Some guys that I work with like to use a wet cloth to remove any excess glue before it dries. But this can backfire and penitrates the wood leaving residue and doesnt stain either. I cant see any drawbacks from using wood glue in a box. But if it doesnt have any signs of need IE loose joints I also dont see the point in it. Another thing to look out for that I learned the hard way is not to put too much reinforcing wood into the box, because the box might seem fragile, because this takes away from the cavity of it and changes the tone. For an accustic guitar it really affects the sound. Not as much for an amped one.

Because I build and sell many CBG's and DB's a year ( about 300 or so far this year) I cant afford to have even 1 come back that didnt hold up.With the internet for communication now days just 1 dissatisfied customer can hurt your reputation .
So because of that I tend to over build sometimes.
I tell my customers that their wife could smack em over the head 5 or 6 times and the CBG will be fine, but you still cant leave it out in the rain,,,,

I'm glad to see this question! I was wondering, myself. I'm no expert, but I seem to have seen somewhere that floppy boxes can also dampen sound. So on my one-and-only ever build, a somewhat flimsy Romeo y Julieta corona box, I put some bracing in to stiffen it up,hoping to *improve* the sound.

Have I just made things worse, then?

for what it's worth i am in agreement with max. I have never used glue when it wasn't needed. However on cardboard cigar boxes i have used gorilla glue to add extra support in the corners, with good results.

Just putting glue in the corners isnt really going to do you all that much good. It would be kind of like smearing super glue on the outside of a crack instead of between the two pieces of whatever is cracked. If you have to reinforce a box though I think that it would be best to add a right angle triangle using glue and a clamp in the corners from the bottom of the box to the top. Looking at it as a box lying on its back with the top open. This will give awesome reinforcement with minimal itnerfereance to the inside of the box.This is done in cabinetry all the time.
