Basses: He often played a German upright bass which he bought just out of high school, but his main instrument was a 1962 Fender Precision Bass known as "The Funk Machine." He kept the action very high, never cleaned it, rarely changed the strings (only if one broke), and didn’t maintain the truss rod, so the neck was warped. On the heel of the neck he had carved the word "Funk." This guitar was stolen just before his death and has never been found - it remains a Holy Grail of collectors.
Amps: Live, he used an Ampeg B-15 and a blue Naugahyde Kustom. In the studio, he almost always went directly into the board.
Strings: LaBella, heavy gauge flatwound.
