As the Nevermind tour concluded, Cobain fancied a change and ordered a bunch of Mustangs. Fender’s Custom Shop weren’t tooled up for lefty Mustangs, so they gave the job to Scott Zimmerman, a prototype builder for Fender Japan. One of these, a sky blue model known as the Skystang III, became Kurt’s favourite guitar from In Utero onwards. His tech changed the pickup to a Duncan JB and added a Tune-o-matic bridge, making another grunge legend.
