Boy, are you lucky. I have two '90's Gibson flat tops, I bought brand new, a '96 J 45 and a '97 Custom AJ with early Jumbo body dimensions with not a drop of glue out of place. They sound great, but not as great as my '42 SJ, my '44 J 45 and my '49 SJ with glue seemingly seeping out of every internal joint that is visible thru the sound hole. The older you get, hopefully, the more you'll realize what I'm trying to say. Have fun with the scraper or razor blade. Neither will improve the guitar,unless if'n all you are content with is the visual aspect of it.
