Unlike Fender's other three big instruments (Stratocaster, Telecaster, and Jazz Bass), the American Precision Bass model wasn't released until 1995 (all other models were released in the mid- to late 1980s). They have continuously produced a standard American Precision Bass since 1995, but there are three distinct models within the series. The first series was called the "American Standard Precision Bass" and produced between 1995 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 a non-veneered body, rolled neck edges, a rounded body radius, a graphite reinfoced maple neck, cast/open-back tuners, and a three layer parchment/black/parchment pickguard. At the Winter 2008 NAMM show, Fender introduced the third round of the American Precision Bass, and the name reverted back to the old one as the "American Standard Precision Bass." Changes include a new High Mass Vintage bridge, new tuners, a new tinted neck treatment, thinner finish undercoat, and all basses come with an SKB molded case. In spring, 2012, Fender introduced the fourth version of the American Standard Precision Bass with the major change being the introduction of Custom Shop pickups.
