Nice looking 4003, Ed. You add the thumbrest?
Actually, I just never removed it. I got that Ric in trade from a friend who bought it new but never could get comfortable with her, he had the thumb rest added in pursuit of that goal.
I ended up selling it off myself, probably a year or so ago during a "don't use it-sell it" purge. I had no problems with playability, with the exception that it the only bass I've ever had that would snag my wedding ring on the edge of the fretboard, and it sounded great, but it never left the house.
Of course, whenever the subject comes up I kinda wish I still had it...
I'll probably end up buying another one, regretfully it wouldn't be the first time I've done that.
