Push the vintage knob back down, and select the pickup selector to both pickups. Now you will get a VERY scooped sound with less mids especially around the area you say is dead.
Play that dead note, then with both pickups on full, roll back the neck pickup knob until your signal gets a slight boost. Thats what worked for me, and grats on the new Ric I got mine 2 weeks ago too!
Also the nut is probably cut really bad, I know mine was.
