Is it a solid color instrument or natural/burst finish?
What you will want to do is cut your block, slightly bigger than the existing rout. Then make a template that your block fits into very tightly. Then clean up the existing rout with the new template and glue in the block. Titebond or any other good wood glue will be fine, Just be sure to clamp it in place. Just use a thin layer because there wont be any room for squeeze out on the bottom of the rout. The glue joint will be stronger than the wood itself.
The more time you spend fitting the block to your template the better your completed job will be.Don't try and make the corners of your rout square, its much easier to round off the corners of your block to fit the radius of whatever router bit you use to do the rout.
If it is a sold color, I would make the block out of a tight grained hard wood that finishes easy, like maple or alder. If its a see through finish you will have to find out what kind of wood its made from or the end result will look very bad.
