This new numbering scheme was short-lived and was replaced only a few months later by an improved scheme that identifies an instrument's country of origin and year of manufacture in the body of the serial number.
This new scheme uses the letters MX as a prefix to designate an instrument made in Mexico, followed by an eight-digit number.
These serial numbers did not identify the country of origin in the body of the number.
Instead, the instrument’s country of origin appears on the decal on the back of the headstock, near the serial number.
Instruments made between 19 carry “MN” prefix serial numbers, with the “M” designating Mexico and the “N” designating the 1990s.
