While performing I will often pound out some of the beats on the face of my guitar. Last week I was doing so and suddenly heard a loud pop-like sound emanate from my guitar. Since then, I haven't noticed any change in the sound or performance of my guitar but I'm wondering whether a glue joint has popped on some bracing, what the implications of such an event might be, who be qualified to do the repair, as well as, how it would be undertaken. Can I do the repair myself?
