Hi all, First post in the luthier forum for me... Tried to search but I didn't really find anything that relevant for me (as a registered user only, the search function isn't the best either...) Anyway, I bought a fretless Squire vintage Mod jazz bass a week ago and I'm not completely satisfied with the smoothness of the fretboard. The fretboard is Ebonol with inlaid white Celluloid fretlines, and it feels like the problem is the fretlines are too high. What can I do to correct this? I'm thinking of grinding it, but I have no clue about what kind of sand paper I should use, if that's even the right tool for doing it, that is... Any tips? I think it's a pretty easy job, I just want to do it right, I love everything else on this bass so I don't want to destroy it. I know a luthier, but I would like to do this myself to save some money.
