The Mustang was built under contract in Japan by Scott Zimmerman of FujiGen, as the Fender Custom Shop was unable to make a left-handed Mustang at the time.
Fender ordered 10 Mustangs in total, six in Fiesta Red and "Sky Blue" finishes being sent to Cobain. The guitar that was sold by Julien's Auctions was one of only two to have the "Offset Contour Body Patented" decal on the headstock.
Cobain had made some modifications to the electric guitar, his tech fitting a Gotoh tune-o-matic bridge and installing a Seymour Duncan JB-1 humbucker in the bridge position.
The electric guitar was sold as part of Julien's Icons and Idols: Rock 'N' Roll collection, which saw Eric Clapton's 1988 Guild GF-60NT go for $25,600 and Chris Cornell's 1993 Gretsch Duo Jet fetch $65,625.
Other stage ephemera went under the hammer, too, including Kurt Cobain's mohair cardigan, which even allowing for the overheated market for vintage clothing went for an incredible $334,000 – a world record for a cardigan. Though Cobain did wear it on MTV Unplugged.
