I like to think that I know a good amount about the fender bass,but this one little enigma pertaining to the 2 basses I listed above has me stumped. I own a 85 Japanese jazz special(1 P bass p-up,1 Jazz p-up),while I owned the same bass but it was called a P-bass special,what gives ? My research has led me no-where,it does'nt have to do with one having a pick-gaurd and one not,nor is it about where it was made or when either,they both have a p-body and a j-neck no matter what model its called. I cannot figure why the same exact bass is called 2 different names,I ruled out all the obvious answers above and still can't figure out the reason. I tried this question on another site and got the reason being that one has a pick-gaurd and the other kind does'nt,but thats incorrect because I have owned both and proved it to be wrong,so if anyone can help out I would really appreciate it, its be driving me bonkers for some time now.
