Rockers Noel Gallagher, Ozzy Osbourne and Rod Stewart will be among 30 musicians designing their own guitars to raise money for charity.
The stars will team up with different artists to have their designs hand painted onto the instruments, which will go on display in various locations around London throughout the summer (07).
They will then be auctioned off in support of the Gibson Guitartown campaign, with all proceeds raised going towards The Prince's Trust, Nordoff-Robbins Music Therapy and Teenage Cancer Trust.
James Blunt, who will also be taking part in the campaign, says, "I am really pleased to be associated with this amazing project which aims to raise lots of money for three fantastic and worthy charities."
Other musicians getting involved in the charity work include Paul Weller, James Morrison, The Kooks, Razorlight and Dirty Pretty Things.
