The Warwick Streamer Stage II was introduced in 1987 (with the 5 string version added in 1989). The Stage II is similar to the Stage I, although it is slightly modified, but with some features of the Thumb bass (like the recessed neck-through construction). Stage IIs from the 1980s are relatively rare, especially the 5 string instruments which are particularly sought after.The Warwick Streamer Stage II has a double cutaway contoured afzelia body Afzelia body. The neck is a 7-piece combination of Ovangkol and Afzelia that runs through the lower half of the body and is fitted with a Wenge fingerboard (or ebony in pre 1994 models) with pearl/abalone Tao inlays. Pickups are two MEC active J/Js with MEC active 3-way electronics. Some examples have Bartolini or EMG pickups - these were an option.
