So, the top and bridge on my abg are starting to lift up a bit from string tension. The bridge and top go back to their normal position when the strings are removed. I am guessing that this is caused by a failed glue joint between the top and some bracing. It would probably cost more than the bass is worth to get it repaired by a luthier, so I am gonna have to fix it myself. What would be the best way to go about a repair? I have a pretty good selection of hand tools.
