I just picked up a great playing and fantastic soundng 1983 Fender Jazz today (swapped for my T-bird)...I didn't realize this until I got it home, but it has a 5 digit serial number. It reads: E 323XX. Now according the fender website and most (but not all) pics I've seen of other ones of this same year its supposed to have another digit in the number. Can anyone explain? I'm sure there's a thousand and one better fender experts on here than me...so any help would be appreciated. Thanks in advance.
