In 2008, the American Series models were replaced by a new American Standard line, which greatly differs from the first-generation American Standard Series basses introduced in 1994. The 2008 American Standard Jazz Bass retained the "American Series" rolled-edge neck with highly detailed nut and fret work, as well as the familiar rounded body shape with the vintage body radius, but deleted the S-1 switching system and incorporated a new high-mass vintage bridge, Hipshot lightweight vintage-style tuning machines, a richer and deeper neck tint, gloss maple or rosewood fingerboard and satin back for smooth playability. It also has a thinner finish undercoat that lets the body breathe and improves resonance. In March 2012 Fender updated the American Standard Jazz Bass (except the five-string version) with Custom Shop 1960s Jazz Bass pickups.
