Yesterday, at rehearsal, while standing, I was adjusting my strap locks and my Strat came loose and the headstock swung down and made contact with the carpeted floor, cement under the carpet. The neck did not snap off, thankfully, and in truth, remained in tune, but I dd notice a crack in the lacquer along the truss rod skunk strip. There does not seem to be a crack in the wood itself. I completed the entire rehearsal, with no incidence, or even getting that far out of tune Do you think I did any serious damage? What should I look for? Thanks.
