Crack

Three years ago, I bought an amazing Takamine acoustic guitar on Ebay. Got an amazing deal too, about $600 off the MRSP, as it was a 'factory second'. That implies that there was some sort of imperfection, anything from a blemish in the woodgrain finish to the headstock falling off and being glued back on.
A couple of years ago, a friend was playing it and noticed a hairline crack in the finish. It was so small that I'd never noticed it before. That was probably what qualified it as a 'second'. No biggie, it still looked and sounded perfect.

Last night Toronto had one of the worst storms I can remember. I watched the black clouds race across the entire horizon in about 3 minutes, my patio furniture was smashing against the railings, and I saw half the city lose power.
I had been watching the TV and stopped strumming the Takamine to set it on the couch beside me. As the storm raced in, the air pressure must have changed. I heard a loud CRACK coming from the far side of the couch. I saw the hairline crack suddenly quadruple in size.

Tomorrow I'm bringing it to Capsule Music for a repair estimate. I may have left it too late, but even if I have to pay a few hundred dollars it'll still be cheaper than if I'd paid full price. But if anyone can fix it, it'll be Capsule...
