Paul McCartney pays musical tribute to amp pioneer Marshall

Sir Paul McCartney has paid tribute to guitar amp pioneer Jim Marshall by posting footage of an impromptu jamming session online.

The Marshall Amplification founder died at the age of 88 earlier this month (Apr12), and stars including Slash and Huey Morgan were quick to recognise the rock icon.

Beatles legend McCartney has now added his own tribute by uploading a video of himself playing guitar during a session with some of his musical pals to his official YouTube.com stream.

In the clip, he says, "This goes to to the family and the friends of Jim Marshall, who passed away recently. The great Jim Marshall, founder of Marshall Amps. Jim made it loud. We wanna thank everybody, we wanna thank all his family, we wanna thank Jim mainly. Man, we love you. Our tribute to you..."
