I would like to know a little bit about bridges. I've noticed that most of them have a rare pattern, a kinda marbled figure. Why's that? Does anyone know? Is it because they use a different wood or it is cut in a different way. I just happened to see a cheap bass of a friend of mine that didn't have that figure, but sort of lines that run parallel to the top of the instrument. Does it have to do with the quality of the bridge?? Thanks, T.R.
