Early editions of the Headhunters did not include a guitarist. All guitar-like parts were handled by Hancock on his first two albums with the group, with one exception: the "rhythm guitar" heard interacting with Hancock's synthesizer bass early in the track "Chameleon" is Jackson playing in the upper register of the bass guitar, as pointed out by Steven F. Pond in his book "Head Hunters" (2005). Electric guitars were first introduced when DeWayne "Blackbyrd" McKnight appeared on "Survival of the Fittest".
