I've restrained myself in commenting on that pencil bass on TB, he posts it all the time. Great pic, Denis! There's a reason that thing lives at the bottom of the ocean!
Surprised someone hasn't just put a strap button into the neck at the 12th fret.
Seriously if neck dive bothers you so much, move the button to the back of the headstock ( I think its called the Hootenany Button or something similar IIRC) like on 57- circa 62 Fenders. But that would make you look foolish...as opposed to having a pencil sticking out of your bass body with a strap on the end.
