Has anyone else noticed that the newer Ric 4003's sound different than the older 4001's? I know what you all are going to say: Pickup placement was different for the neck pickup, different truss rod system, that 3rd Cap in the electronics, whatever else. I mean that the newer Ric's sound bassier, well at least to my ears. Today, I decided to change the pickups in my 2002 Ric 4003. I had a set of original pickups from a 1972 Ric 4001 just lying in my parts drawer. I put them in the 2003 and WOW, what a difference it made. The bass just seemed to come alive. It sounds more like an early 70's 4001 now. Apparently, Ric also changed their pickup design. Maybe in the winding, maybe the magnets used. I did notice a few differences between the older pickups and the newer ones; 1. The pole pieces on the older ones are smaller. 2. The neck pickup is physically thinner from front to back on the older ones. The length and width are the same for both, so the older ones fit in the same hole. 3. The material used to make the black bobbins on both the neck and bridge pickups are different from the newer ones. 4. The portion that holds the magnet and bobbin on the old pickup is also different than the new one.
