Here is a list of the tools that I am using. Your list may vary. There are often many ways to complete a woodworking project (and let's not even get into excoriating felines). This is simply how I did it and what I used. As well, I am using cabinet grade Baltic Birch plywood. You may use something else if you wish, though I cannot speak to acoustical properties of anything other than this. Cabinet grade is important for a nice finish and to avoid gaps that would need to be filled.
Contour sanding grips
Anything else I forgot
3/8" Baltic Birch plywood

Yes, I consider glue a tool. Deal with it.
