G&L SB-2 Bass Guitar Neck

Neck has a nice worn in feel in my opinion but it has a crack between the nut and the 1st fret. See photos. I had a repairman look at it and he put some glue in and I think around the crack. I felt kind of hesitant to tune it up to pitch and have the neck be under full string tension so I haven’t tuned it to pitch. Not sure if it could benefit from a more extensive repair or what exactly that repair would be.

I believe this is a 1983 neck from the stamp.

I believe this was made in Fullerton California USA

It was with a 1983 G&L Sunburst Body I have listed also.
