The pretty bridge blanks in the middle are Madagascar rosewood. It has the beautiful depth, color, contrast and tone of the now hard to get Brazilian rosewood and you can get it reasonably priced. We just scored another small pile to add to our stash. To the right is ebony and left Indian rosewood.
Featured in the center is a plastic bridge that many early Gibson flat top acoustics came with. That is one of the many reasons we keep so many bridge blanks in stock. The other reason, sometime when we are doing a restoration on an old acoustic and have to make a new bridge we may want to try to match the wood of the old bridge to keep the same look.
Here are a couple of past blogs of bridge replacements.
