i bought fender jazz bass off a friend. he claims its a japanese body and MAY be a squier neck. but the body is clack with a sparkle finish (which ive never seen on a real fender) it has a string thru body bridge and the neck pocket says JB BM 81/2 4. is it a real fender? also the neck lofo is worn off the headstock but it has a gold fender 50th anniversary sticker on the back and the bottom just reads SEP1996. any clues?????
