Fender has continuously produced a standard American Stratocaster since the mid-1980s, but there are three distinct models within the series. The first series was called the "American Standard Stratocaster" and produced between 1988 and 2000. At the Summer 2000 NAMM show, Fender introduced the new "American Series" that was announced as an evolution of the American Series. Changes included American Deluxe body specs with a historically correct upper horn and non-veneered body, HSH pickup rout instead of the old "swimming pool," American Deluxe neck shape with rolled edges, Deluxe Staggered tuners, original headstock shape, custom staggered pickup magnets, three-ply parchment/black/parchment pickguard, and parchment pickup covers, knobs, and tips. At the Winter 2008 NAMM show, Fender introduced the third round of the American Stratocaster, and the name reverted back to the old one as the "American Standard Stratocaster." Changes include a new bridge with bent steel saddles, a new tinted neck treatment, thinner finish undercoat, and all guitars come with an SKB molded case. In spring, 2012, Fender introduced the fourth version of the American Standard Stratocaster with the major change being the introduction of Custom Shop pickups.
