Diki, according to his bio and old publicity from Gibson Guitars, Howard Roberts took credit for the studio wah wah in Shaft.

At least that's what I've read over the years. Howard, as you know, was one of the world's most prolific jazz and studio guitarists. I have several Howard Roberts designed Gibsons in my collection and many of his albums.
