) : If you can tell me a site where this info can be found I'd be most grateful.
MZ refers to "Mexico Zero", that is any guitar made from 2000 onwards.
I've looked at a number of sites, but I can't find a year of manufacture for a Fender Stratocaster made in Mexico with a serial number that begins with MZ.
(I presume this isn't MN and the N is on it's side??
When I toured the Fender factory in California in 2001, there was discussion about a possible limited edition Custom Shop replica of Number One.
At that time, it was suggested that there might be as few as four replicas made.
CC 6 digits corresponds to Walnut Stratocaster 1981-1983.
