He is talking about the 'dip'. If you sight down the board, it really is interesting... it dips just a touch and then comes back up a bit (or seems to). Disturbing until you realize that it is supposed to do that! It really does look like a little 'valley in the end of the board'.
Just curious, I don't seem to wear frets out on my basses so I've never felt that my Sadowsky's needed fret crowning.
If I were to take my Sadowsky to a local shop for fret crowning do you think that they would take the "dip" into consideration in the crowning process? Or would they need to be informed prior the work?



! If there were other issues it might be worthwhile.
