Jacobs (August 25, 1963-April 22, 2021), known by the stage names Shock G and Humpty Hump, was an American musician and rapper. He is perhaps best known as the head vocalist for the rap group Digital Underground, most popular in the early 1990s.

Jacobs spent most of his childhood moving around the East Coast with his family, eventually settling in the Bay Area of California. He dropped out of high school in the late 1970s and spent several years pursuing a life of crime before eventually finishing his degree and attending college, where he studied music.

In addition to his work with Digital Underground, Shock G has found moderate success as a solo artist.

In 1993, Shock-G produced Tupac Shakur's breakthrough gold single "I Get Around" as well as guest starred on the single and music video, and went on to produce Tupac's "So Many Tears" from his album Me Against the World. Tupac's first published work was while still a member of Digital Underground when he appeared on the song and video "Same Song", which also appeared in the Chevy Chase,Dan Aykroyd and Demi Moore film Nothing But Trouble. Shock also co-produced Tupac's debut album 2Pacalypse Now.

In 2004, Shock released a solo CD, Fear of a Mixed Planet.

In July 2005, Shock G announced that he was retiring from studio work, citing the fact that too many people were asking him to work for free. He will continue to write and tour, and he has also expressed interest in acting and playing with other music acts—as long as it's not for free.

Shock G's production credits include several gold and platinum Digital Underground and 2Pac releases, as well as songs for Prince ("Love Sign" from the Crystal Ball LP), Bobby Brown, Saafir, and others.
