That scratchplate shows use, plain and simple. Regarding the nut, before fettling my own (it was high for my preference), the strings sat much lower than shown above, with none of that burring and with squarer shoulders. That one looks suspiciously like the strings have been used as a makeshift file. Bass Direct have a white, used one for £550 if you’re interested (hopefully the above isn’t that one). My only proper niggles were that the foam under the pickup wasn’t robust enough to stop it moving around under normal thumb pressure (I like to anchor my thumb there when playing the E) and that there was bit of slop in the tuners, they held well enough, but felt cheap. Extra, more sturdy foam under the pickup and a set of used Hipshot tuners fixed both of those issues. I also lowered the nut slots and rounded the shoulders off, redressed the fret ends after ‘rolling’ the fretboard edges and polished the frets (some were rather dull), but this was for my preferred setup, YMMV.
