Ad's, while they are at it they need to do something about that tail block. it is way to thin. It needs to be at least 25mm thick if it is going to provide adequate support to the guitar strap pins. Plus it should be shaped away from the top/ soundboard and the back of the guitar. by not being shaped, there is a strong likelihood that the wood above and below the ply will crack as the tail piece breathes (expands and contracts).
This is what a finished block should look like at the tail.
