1. Buy a new neck and move on with your life.
2. Cut the little fucker off. (it can be expensive depending on how well you want it done).
On this neck It was for aesthetics and love how it turned out. Just be aware that some of the old fret slot needs to be filled, sanded and polished. I used a silver of maple and wood glue to fill it. Then the next day a spray of sealer to finish it all.
Precaution: the 22nd fret is on an overhang so cutting it off will not affect the scale length. And as always, please please use caution and make sure you understand scale length and wood working. If you dont, just pay someone qualified or buy a proper neck!!!!!
