I’m incredibly fussy with my basses, that’s just some shading in the grain, I’ve got it on my 98 P bass, it wouldn’t bother me , if it was a knot I wouldn’t accept it 🙂, can we see the whole bass 👍
Just to add, it can also depend on the tort, I had one on a natural jazz and it didn’t look that good because it had too much red, I changed it for a darker red/brown tort and it looked great
