So I picked up a cheapo Yamaha for $5 at a garage sale today....with the intent to repair the soundboard, so It will become a decent beach/campfire guitar. I'm not worried too much about how it looks, because it will be a beater, and sound quality is not a big issue either. I just want to be able to re-string it and play it. I've been able to find information on removing and replacing the bridge, and bridge plates, however the previous owner took such great care of this instrument, that when the bridge cracked, it continued to pull up the soundboard, creating a nasty bulge, and tearing apart the soundboard beneath the bridge. Any advice for repairing this, so that when I go to attach a new bridge, it holds up?
