As the listing says, that guitar is made of ash- hence the distinctive big grain pattern, and the sandblasting further enhances the effect. Never seen ash anything like that colour, so presumably that is a stain.
The appearance is entirely down to the material. If the luthier is using another timber for the body, you are going to get what you get. Unless you can find someone to paint the guitar to get this effect- it is tricky, but can certainly be done. Whether it lasts is another thing
