I picked up a 2nd hand Japanese Jazz which has on the front of the headstock the following: Fender Jazz Bass and "Made In Japan" under the Jazz Bass logo. The serial number is on the heel of the neck. It begins with "R" followed by 6 digits. Looking on all the sites, there is no "Made in Japan" with a "R" + 6 digits serial number, there is only the "Crafted In Japan" with the "R" + 5 digits serial number. Any ideas on how to decipher this Japanese Jazz Bass? I'm totally stumped!
