The bridge on my 4 string fretless doesn't want to stay in. At first I tried putting tooth picks in the holes then screwing it back in, that worked for a little while, but it ripped out again. So this time around I tried mixing wood glue and baking soda along with another toothpick to try and keep it in, that only laster for about 2 weeks. So now I am calling out to you setup gods for help! What are some other things I can do to keep this damn thing in?
