Damon Albarn's main electric guitar, a 60's Olympic White Duo Sonic II. Bought sometime around 1997-1998, This guitar was used on the first three Gorillaz albums, Blur's Think Tank, Mali Music, Africa Express, The Good, The Bad, & The Queen, etc. He played this guitar for over 14 years until 2011, when he replaced it with Graham Coxon's signature Telecaster. The whereabouts of this guitar are unknown, but he still likely owns it and plays it.

Lee Ranaldo is confirmed to have used a Fender Duo Sonic II during Sonic Youth's performance of "Mildred Pierce" in August 1990. For this performance, Lee borrowed the Duo Sonic II from the opening band, STP, as the song required standard tuning. This is supported by footage from the music video shoot, where he used this specific guitar on one of the two nights.

Jeff Wooton played Damon Albarn's Duo Sonic II during the Escape to Plastic Beach Tour, the guitar was mostly used as his backup to his Fender Jaguar. However, this was his main guitar very early in the tour. This guitar was later used in the tour by Simon Tong.

"The DuoSonic was the real guitar. The DuoSonic was the main one, and that’s somewhere in the Rock and Roll Hall of Fame right now. I feel bad about that, but not too bad. It got played, it went underwater. It’s done some things"

Simon Tong frequently played Damon Albarn's 1960's Fender Duo Sonic II. He played this guitar throughout the entire The Good, The Bad & The Queen's first album, and was last seen with it playing with Gorillaz in 2010 as an additional guitarist. The way you can tell this is Damon's is because its age and wear pattern is identical, and also the placement of the decal.
