Despite your preference for Fender, you just described a G&L JB-5. It slipped my mind, but I've owned a JB-5 and it had a very nice feeling neck (1.77" nut width on those). String spacing was a little tight for me, but not out of the question after playing EBMM 5-strings for several years. Didn't particularly care for the 9.5" radius either (I'd opt for their 11" radius if given the option), but it was a great bass with a very comfortable neck. There was word that they were working on making a 19mm string spacing version, which I'd definitely like to try.
