String won't stay in nut slot

[SilGarzaJr]

If the perspective of that photo isn't distorted, return it. That neck appears to have a serious twist starting.

I wouldn't mod it at all if it's a brand new bass. Return. Good luck with whatever you choose.

I thought the same thing when I saw the first image. Major neck twist!

If it's a new bass, take it back and get another one.

Same here, something doesn't look right with that neck.

Make sure the nut slot is at least half the depth of the string, but preferably more.

This. Also - you changed the strings from rounds to flats. Are you using a heavier gauge? The new string may be larger, or have a higher tension. If the top of the nut is low, the new string may want to pop out. I would have checked this before doing anything else.

There's actually some good ergonomic engineering in it. But it's not without it's own set of problems. A twist in the neck will not present a problem on a properly configured instrument if the line on the fingerboard below each string is truly flat (or actually with the proper relief). Even if it is, there is a problem with a conventional trussrod in such a neck. The trussrod can do an adequate job in a single plane, but if that plane is rotating there's not much chance that it can be effective in all vectors. Fret levelling also becomes a big deal. It still can be done, but there's a whole other level of complexity involved.

I personally find that the ergonomics don't work for me and certainly aren't worth the aggravation. YMMV

I admire the engineering but it takes some getting used to looking at it and problem solving playability issues could be a tad confusing if your tech has never seen one before.
