Revered soul guitarist, Charles 'Skip' Pitts, died on Tuesday in Memphis after a long struggle with cancer. He was 65.

The musician was best known for his distinctive 'wah-wah' guitar pedal sound, memorably featured on Issac Hayes' theme for the 1971 film 'Shaft'.

The blues guitarist joined Hayes' band in 1970 and remained a member until Hayes' death in 2008.

The Stax Museum of American Soul Music said that the musician had been suffering from lung cancer, the BBC reported.

Born in Washington DC, Pitts learned to play guitar when he was 11 years old, picking up tips from neighbour and fellow musician Bo Diddley.

By the age of 17 he performed on Gene Chandler's Rainbow '65 and went on to play with the Isley Brothers, Sam and Dave and Wilson Pickett.

It was his move to Memphis and his near 40-year collaboration with Hayes that earned him his fame.

Later in his career, Pitts made appearances in films including Samuel L Jackson movies 'Black Snake Moan' and 'Soul Men,' to which he also contributed soundtrack entries.

He also performed on the score for 2005 film 'Hustle and Flow'.

Most recently he worked as a session musician for Stax Records and appeared on Al Green's 'I Can't Stop' and Cyndi Lauper's 'Memphis Blue's, both of which were nominated for Grammy awards.

He also released an album last autumn, titled 'Got to Get Back!', with his band 'The Bo-Keys'.

Scott Bomar, his Bo-Keys bandmate, told Memphis website 'The Commercial Appeal' that Pitts' style was "very unique".

"He took a little bit of the Bo Diddley rhythm, the Northern soul of Curtis Mayfield and the Memphis sound of Steve Cropper and Reggie Young and somehow came up with his own thing, a style that no one had," Bomar told the website. (ANI)
