Hi everyone, I've been reading along here on LT for a while now, it's been super helpful. Now I want to share some of my builds and also seek out your expertise. I've built a couple of electric guitars, but currently I'm working on my first bass. It will have a Billy-Bo shape, similar to this guitar that I built earlier this year. It's a 4-string and scale length is 34". The bass neck is already rough shaped, it is a laminated 4-piece mahogany neck with Maple/walnut/maple veneers in between the mahogany. The fretboard is Ziricote. Unfortunately, I placed the volute a little bit too far back into the headstock (see picture below). Damned! The neck is fairly thick, 22.5mm at the nut (incl. fretboard). It is reinforced with two carbon strips 6x6mm, but they end just before the end of the fretboard. With the cutout for the trussrod nut at the headstock (9mm deep by 8mm wide) I am wondering if the transition between neck and headstock will be strong enough. It is 16 mm thick just behind the nut and 40mm wide. Oh yes, and it's scarf jointed. On a guitar I probably wouldn't worry about it, but what do you think for a bass? How much more tension do the four bass strings put on the headstock?
