If he really wanted to make it look, and sound, more authentic, he should have moved the bridge pickup back to the bridge. I would have done so.
It always makes me wonder about people who irreversibly mod their basses and guitars then turn around and sell them.
True, but that would entail a massive amount of extra work, including a re-fin.
