Fans and musicians alike are mourning the death of music icon Jim Marshall OBE, the inventor of Marshall amps.

Marshall, affectionately known as the Father of Loud, owned a music shop in London before he went on to found Marshall Amplification 50 years ago.

Marshall amps found favour with leading guitarists down the decades including Jimi Hendrix, Pete Townshend and Nirvana's Kurt Cobain.

A statement released via his official website read: "Jim rose to become one of the four forefathers responsible for creating the tools that allowed rock guitar as we know and love it today to be born.

"The groundbreaking quartet also includes the late, great trio of Leo Fender, Les Paul and Seth Lover. Together with Jim, they truly are the cornerstones of all things rock."

While the music world pays its respects to Marshall, IB Times UK looks at the other pioneers, whose inventions and foresight changed the face of music forever.
