There will be a bevel in the place you've circled, then it blends to the top flat part so there's a place to mount the nut.

Thank's to take time to give me explanations. Is the bass ready now ?    

Hi Mica, is my bass completed ?  

Mica, I was waiting for my bass in my mail box because it's MY BIRTHDAY today

Incredibly cool bass wood selection.

Happy birthday! It always takes a little longer than you might expect, but as you know, it's worth it in the end!

Don't be so sad, your Bass is going fairly fast compared to some (poor Austin...).
