I've got a Washburn acoustic bass AB10 and the bridge has come off the body. The glue has failed and I can see two screws that are still slightly holding the bridge onto the body. Any ideas how I can fix this? The AB10 does not have a hole in the body to get at the inside underneith the bridge... I've never done any of this before and I would like to try to fix it myself. Any ideas? Do I simply drill the pearl plugs to get to the screws, take it off, sand it down, and then reglue? Any help would be amazing!
