This is a local musician's main acoustic. It's a 2014 Gibson J-29. As you can see the bridge was lifted when I got it, and the top has been pulled up into a bulge. The bridge came off pretty clean, but I noticed how the spruce broke behind the pins. I didn't score this side of the bridge, but it looks like it must have been scored for the wood to break that cleanly. Could this have come from the factory like that?

I don't know why Gibson would use such a narrow bridge on a steel string, it really reduces the glued area.

Is the best thing to do here to try and just glue the spruce back down and hope for the best? I also need to try and flatten the top. The bridge is perfectly flat on the bottom.

I'm curious as to why there is about a 1/4" plugged hole near the middle of the bridge.

The guy says he's owned this about 8 years and doesn't know of any work done on it before.
