So I was changing the strings on my bass. As I'm tightening up the first string, the bridge begins to pull completely out of the body by the progs holding it in place. I'd give you pictures, but I'm too poor to afford a camera. Which is why I'm posting this: is this something that is going to require major repair from a professional (christmas time, yeah), or could I handle this one myself (with limited knowledge of the technical side of bass guitars). Basically, any advice and experience with this situation would be appreciated. Also if you don't know what I'm talking about, google an Epiphone Thunderbird and check out the bridge setup.
