Note: Not the "Blue Courtney Telecaster"

Cobain's last favorite guitar was sold to a private buyer by rockstarsguitars.com

Note that on the photographs of Cobain playing the guitar the pickups are different. This is because Earnie had modified the guitar.

See quotes below:

From rockstarsguitars.com:

"This is the guitar that Kurt wrote his music on and carried with him for months from bus to hotel room to airline toward the end of his career. This guitar was not exclusively used for live performance but more for writing and never left his side. It was used from late 1993 until his death in 1994. It is featured on the cover of the book "Nirvana" and on pages 116-123. There are distinguishable markings on the body that can be matched up perfectly with these photos. It also comes with original prints of Kurt playing this guitar and a notarized detailed letter from a crew member. The pickups, bridge, and tuners were changed at one point, as this was a common practice with Kurt's guitars. This was done by Earnie Bailey, Kurt's guitar tech. This comes with a letter from Earnie detailing the complete modifications done to this guitar. Earnie also supplied the original receipt for the bridge pickup and a letter from Gibson for the neck pickup that he installed, and has signed photos of this guitar ensuring the authenticity of the instrument. And it still has four of the original strings on the guitar."

From kurtsequiptment.com:

"Sent to Kurt by Fender in early 1994 . Japanese made. "Fender sent this out for the In Utero tour to replace the blue one. Stock pickups were very shrill. After Kurt's coma in Rome, I thought modifying this guitar would make it a workhorse and get him away from the Mustang-Jaguar image. Hopefully get him perked up. I put on new tuners (Gotoh's - his favorite). A Tele bridge from Stew-Mac with a humbucker cut-out and individual saddles for each string. In the bridge, I put a Duncan JB - black, and in the neck, a new Gibson PAF, potted with a Chrome cover. He got this back 2 weeks before he died, and said it was his new favorite. He used it for the home recordings he was making with Pat and Eric Erlanderson in March 1994 in Kurt's basement. "
