A guitar amplifier used by George Harrison on The Beatles' classic albums Revolver and Sgt. Pepper's Lonely Hearts Club Band is to be sold at an auction.
The amp was discovered by engineers who spotted the rock legend's name scratched inside it as they carried out repairs.
It's believed the equipment was given to Harrison in 1966 and was later used on tracks for the Fab Four's iconic 1966 and 1967 albums.
The Vox Ul730 valve amp, which will go up for auction in London next month (Dec11), is valued at $112,000 (£70,000).
