got a new slotted ebony fretboard for 25$ because it had one worm hole.
solution: got a small piece of (ebony in this case) stuck it in a pencil sharpener, glued the pointed end in the worm hole. after it dried, cut it off and sanded it. saved 12$ on the fret board and that was enough to buy an ebony headplate, an extra piece for a control cover and a small pen blank to make a thumb rest out of.
