Ruh Roh, . . . not tryin to be controversial, but:
The pictured neck pocket is a farce. By design, it does not promote a stiff, firm neck joint that counteracts string tension . . . quite the contrary, the way it is, it is prone to weakness. And then it uses only two screws . . . that only worsens the situation.
If the idea is/was to increase "contact area" by sloping the sides of the pocket, then that should have been accomplished by inverting the slope and creating a sliding dovetail joint (something I've thought about doing) that would require no screws at all, and be infinitely stronger!
When one considers the physics of a strung truss, then the problem with this joint becomes very clear.
Now, scuse me while I go duck down . . .
