So, I just picked up a cheap MiM Fender Jazz fretless off of eBay. The bass arrived today, looks ok, seems to play ok, if a little wonky due to some wierd pickup adjustments. I go out and pick up a new set of strings, pop off the old string and oil the fretboard. What do I find? This: I don't believe this is the way it's supposed to be, yes?? Some nutjob has tried to lower their action by filing into the fretboard, yes? I don't believe I'm all that concerned, since it's not in the playing section of the fingerboard, and a new nut should take care of things, but still. Please tell me I'm sane and this isn't the way MiM fretless are made.
