I have an old Vox Acoustic/Electric 12 string with a wasted neck. I would like to remove the current bridge but there are 2 wood plugs/caps that cover the bolts that hold the bridge to the top. I'm not sure if they are glued, but they don't easily come out. Is there any technique/tool I should use to remove these so I can get to the bolts or should I just drill them out? I am going to convert this into a A/E 34" scale bass. TIA.
