The Warwick Streamer Jazzman was introduced in 1999, shortly after its cousin the Corvette FNA Jazzman. The Streamer Jazzman inherited the configuration and body shape of the Corvette FNA Jazzman but the Streamer Jazzman top is flamed maple (as opposed to Acer for the Corvette). The Streamer Jazzman is also available as a 5-string, and was perhaps Warwick's biggest selling bass in the early 2000s. The first Streamer Jazzmans had Seymour Duncan preamps with a switch to activate an EQ circuit that shapes the output to a special "slap style‟ sound. From around 2001 a MEC preamp is standard ( without the shape switch). The Streamer Jazzman is so-called because of its pickup configuration with a slanted Jazz Bass pickup at the neck and a Music Man humbucking pickup near the bridge.
