    Ok not sure if this is the right thread for this but here goes. I have an old acoustic guitar that the neck brace block has come loose. I need a durable permanent wood glue but then I am worried about affecting tone transfer and resonance.

    I will also be having to do some L bracing corner bracing around this neck block and inner body.

    I am wondering if Gorilla Glue is a bad idea? I used Gorilla Glue on a shattered broken guitar neck about 10 years ago anf that thing is holging up like a champ.

    Elmers wood glue works works great for that. The tighter you clamp it the better

    I was wondering about regular wood glue holding up over time. This is the old dreaded Epiphone acoustic with the bolt on neck. I read somewhere it needs to be along the lines of some mixed epoxy. I figured gorilla glue would be easier than having to mix up epoxy.

    I know there's Titebond wood glue that has additives.

    Mainly wondering if any of these glues will mess with resonance and such. It is a very warm sounding guitar.

    Yeah I will be doing some multi stage clamping for sure.

    I have a Gibson acoustic, and the walnut bridge was lifting. I stuck Gorilla wood glue underneath the bridge, and it's been solid. While obviously different from gluing the neck, I've noticed no tonal change.

    Cleaning the old glue off is the hard part down to the wood.
    To maximize adhesion bare wood should theoretically be exposed before applying fresh glue..
    Gorilla wood glue would be an excellent choice.
    Die hard s use hide glue which is melted into a pot. Epoxy is not a great glue for wood but wood glue when dry is stronger than the wood itself.

    Titebond 2 wood glue is what my luthier has recommend to me for any acoustic repairs I’ve needed.

    Yeah, I am leaning towards one of the Titebond types or the Gorilla Glue. Will figure this out soon and try to get on this repair as I am officially on vacation lol.

    Will report back the reults.

    Bummer is I do have a bottle of Titebond here and the last time I went to use it it was dried up in the bottle.

    Well, I just finished adding two braces of 1/2" X 1/2" almost 4" length hardwood using Titebond III, and it is clamped till tomorrow.

    The braces are on each side of the sound hole, short lengths I added on top of the thin bracing that was already there. These braces run same direction/parallel to the neck. The existing bracing was very thin and bowing as the sound hole was sinking in with the tension of the strings. This is an old Japan Epi 12 string but it has only had 6 strings on it since I have had it around 10 years, and the person I got it from only had 6 strings on it stored in a closet for many many years.

    So I am now wondering if those braces are going to change the tone in a negative way? The braces I added are just squared Poplar, but I am wondering if I should have rounded off the edges? The guitar had a very rich bassy tone and we will see what it is like after this fix.

    These are the braces I made to support the huge neck block. They will go up in back top corners behind sound hole, each side of the neck. Help kerp the neck from bowing up. Made them from poplar. Was just going to make L brackets that would have been glued 2 piece from 1x2. Figured these will be stronger as they are made from one solid piece. They measure 1.505 x 1.525 on each supporting wall. Just ovet 3 inches long running length of neck.

    When setting the neck watch the action.

    Hopefully this fix puts it back with low action like it left the factory in the early 70's.

    The body top was sunk in a bit at sound hole near the neck. I want to be able to have it back to a 12 string, which is my main goal here.

    Next I will find if I altered the tone and resonance with my adding of wood inside.
