my ebony board is lifting slightly in the middle section of the neck ! Strangely enough the playability of the bass is not really affected (yet) ! The board by the nut and the end of the neck is still holding strong though. I'm wondering what the correct procedure is to correct this ? Is it possible to inject glue into into the lifted space and clamp it or should one remove the board , have the surfaces smoothed and then re glue the board on ? Also how does a luthier normally remove a finger board ?
