I've used bigger dovetails on a drawer! Pretty colour, though.

Okay, Guys, I can see that you're pretty contemptuous of this joint, but turn this into a "teaching moment" for me and others like me who are not so experienced. Given the fact that it's a thin line guitar, and supposing you could build the joint from scratch any way you wanted to, how would you do it? What would you do differently? Please be specific, or I won't know what the heck you are talking about.
Thanks to all.

The female part doesn't appear to have any wood left to get a bond. Repairing dove tail joints is certainly not my strong point though.

I would go with a joint similar to what is found in some of the kits from China. These kits have decent bodies but the necks are not to great. I built a new neck for one and it came out real nice with a final weight of only 6 pounds 10 ounces. Here is one I am about to start on.

Matt,
Thank you for responding. I see that you favor a "slide in" joint that is probably bolted or screwed in some way. We can't see how that is done, but I have no problems with mechanical fasteners as long as they are fastened well.

In the meantime, I am still waiting for a post from someone who will explain to me how this original dovetail is worthy of so much contempt.

Thanks to all.

The joint shown is set with glue alone. There are no fasteners needed. This is the same type of joint many guitars with a 19th fret body joint have. The wood from the neck extends under the pick up cavity. With all the contact area these joints seldom fail so they are not often seen for repair. The joint does not slide together it simply rests on the center beam and contacts at the sides. The failed joint is way to short to have any strength. With such a thin body ( 1.75" ) the joint needs to have the 3" tab that extends from under the 19th fret.

This was a factory joint. I think the pink goo is some kind of glue.
Sad thing is the company selling this line of guitars sells the busted ones as luthiers specials.
Sure feel sorry for someone buying a new guitar from this company.

The body is usable but what do you do about that green finish. To put a new neck on would be easy enough. But how to match up the finish on the neck to the body? If you want to put the old neck back on the only way I see to do that involves adding a heel extension which may be difficult to fully disguise externally . I think that either way would be to much effort for a guitar like this.

There seems to be plenty of room to make this joint proper.... First, get rid of the pink goo. Then I'd remove the hardware, and rout a longer mortise into the body. Then I'd make a tenon add-on to fit, bolt and screw it to the existing tenon, and then do a proper glue and clamp job. Upgrade that Frankenstein!
