Matt Sharp

"Matt started out in Weezer with some gear that he later called 'awful and embarrassing'. His amp ... was a Gallien-Krueger 800RB. He had it since he was a teenager and it served him well right up through the mid-90's Rentals era. Where it is today is unknown." - Karl Koch, weezer.com

"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

Apparently, one of these amps was auctoned off Ebay in 2010.

In the video "Weezer - Undone -- The Sweater Song" on WeezerVEVO's YouTube channel, Matt Sharp is seen using a Marshall Vintage 8x10 Cabinet that has been converted to a 4x12. This cabinet is paired with the renowned Mesa Mk.1 head.

A photo of Matt Sharp's rig clearly shows him using the SWR Golight 4x10.

In a photo from a Weezer concert on May 19, 1997, Matt Sharp is clearly seen using an Ampeg SVT-VR bass amplifier head, located in the bottom right corner. This usage indicates a shift from his previous use of an Orange Matamp during the January shows of the same year. It is noted that he continued using the Ampeg SVT-VR until his last performance with Weezer on August 15, 1997. This change in equipment may have also influenced the recording of The Rentals' second album, "Seven More Minutes," during the spring of 1997. The proof for this is visible in the photograph provided by Nick Lavallee.
