So, it was made in 75 but released to market in 76?
That's cool, I guess.
Well no, not eaxctly. It was manufactured AND released to market in late 1975, but as part of the new 1976 range launched at that time. As far as I know the whole industry followed that convention, as does the auto industry, for instance. New stuff on offer in time for Xmas?
Anyways, this means that Nov (K), Dec (L) and sometimes Oct (J) serial guitars have the following years specs. Quite often it doesn't matter since the specs don't always change, but sometimes it gets messy.
For instance, in the 1981 catalog, Greco launced a Jazzmaster and Jaguar copy (JM- and JG-700). They must have sold dismally, since they only ever made the batches they needed for the launch in Sept-Nov 1980. So you get two 1981-only models which all have late 1980 serials. Took a while to figure out.
