“Custom Built for Jimmy Page”, as displayed on the front panel. According to this May 20, 2009 Music Radar article, it was sold on eBay that year.

Here at MusicRadar we like a bargain, and we also like a slice of rock history. However, despite pooling our collective resources, we found ourselves about $29,937.25 shy of the 30 grand required to open the bidding on what appears to be a bona fide slice of Jimmy Page's backline circa 1971.

A 1971 200-watt Orange Matamp is a rare beast at the best of times, but this example is claimed to have been used onstage on a world tour by one of the most famous guitarists in the history of popular music, in the biggest band of the seventies. In the great rock 'n' roll memorabilia newsagents, we're talking top shelf.

"He also got a new main amp, a vintage 1967 (?) 200-watt Orange Matamp. However this did not end up on the Blue Album due to its constant fuse popping (later we figured out that it needed a bigger size fuse than what it said on the back).

Later, in 1995, Matt got a second Orange Matamp, which was very similar to the '67, except it was from approximately 1975. It looked almost new, but this was before they started re-issuing them, so we knew it was old.

On 'pinkerton' and on stage for later Weezer and Rentals tours, Matt went back to the GK, with a Sovtek Big Muff pedal for distortion, and used the Orange just for recording clean sounds and for a back-up. Eventually both Oranges were severely damaged - the '67 from the "Rhino Lad" incident during a '97 show in Richmond VA, and the '75 from a bad freight shipping incident. Their whereabouts and current condition are unknown." - Karl Koch, weezer.com
