I'm considering replacing the bridge on my guitar now since it doesn't hold it's tuning very well and the whammy bar doesn't even work with it because it just throws the whole thing out of tune. (also a nice gold bridge would look pretty sick). So I'm looking for suggestions on how to choose which bridge to buy, how will I know if it fits my guitar, and is it easy to install myself, like what do i need to do? it's a fixed bridge by the way on a 1980's flying-v knockoff, thanks
