Jimmy Douglass (also known as The Senator) is an american recording engineer and record producer, whose prolific career has spanned four decades. Having worked for many artists since the 1970s, Douglass has served as the main engineer for contemporary R&B/hip hop producer Timbaland since 1996.

Jimmy Douglass started his studio career as a part-time tape duplicator in the early 1970's at Atlantic Records studios in New York City. At the time he was still attending high school, and working evenings. There he learned how to operate the studio's custom made 16-channel console and observed the work of great engineers, including Tom Dowd, Jerry Wexler, and Arif Mardin. For his first time behind the faders, he was encouraged by Wexler to engineer the session recording for a demo of a new band. His hard work and immense talent have carved a place for him among some of the most respected engineers and mixers in the world.

Douglass is best known for bringing unconventional techniques into the studio, and encouraging artists to transcend genre restrictions. He is credited with bringing a raw edge to a sound, and specifically bringing a heavy funk bass sound into rock music.
