Hard to foretell. They let the American Vintage Series unchanged for 4 decades (1982-2012). A 62 P, a 57 P, a 62 Jazz. The only change made was a '75 Jazz Bass added during the 90s.
It was very popular. You would hardly see any pro with a contemporary Fender Bass, at least far more - if they didn't use real vintage stuff - with one of these vintage reissues.
Then they changed to the Pure Vintage Series in 2012 or 2013. A 63 P, a 58 P, a 64 Jazz and a '74 Jazz. This was a bit more expensive and vintage correct than the previous series, the most noticable change: the clay dots. My favorite US Fender basses.
Then after just about 4 or 5 years, the American Originals superseded the American Vintage Series.
There is a whole lot of bad info in here.
They did not leave the American Vintage Series unchanged for four decades.
First of all, you meant "for three decades," not four, in the range of years that you listed ("1982-2012").
And secondly, there WERE changes in that period, including to the names of the lines.
The first U.S. made reissue series was called the Vintage Series, or U.S. Vintage Series. Circa 1982–1997. It was NOT called the American Vintage Series.
Some specs changes were made (making them more vintage accurate, mostly), and it was renamed the American Vintage Series for 1998.
In late 2012, a major specs re-vamp swept through the line, but the American Vintage Series name remained. It was NOT called the "Pure Vintage Series."
Pure Vintage is the name of the new vintage reissue parts line that was introduced alongside the re-vamped AV Series (the parts that were used on the re-vamped AV Series, that continue to be used on the AO Series, and which are available separately). "Pure vintage" is also a phrase used in the advertising for the re-vamped AVs – but NOT the name of the line.
The American Original Series replaced the AV Series for 2018.
There was never any official distinction between "AVRI" and "AV." "Reissue" was never actually part of the name for ANY U.S. made reissue line. It was called the AV Series from 1998 through late 2012, even though there were two versions of it. And, again, the AV Series did not exist until 1998. It was called the Vintage Series or U.S. Vintage Series before that.
