Did Kurt Cobain use a Seymour Duncan JB Jr?

So, I am trying to build a mustang with the same specs that Kurt's had at the 1993 show at the Roseland Ballroom. I was wondering if he used at JB JR, Hot rails or did he just use a JB Humbucker?

The Roseland mustang had a Seymour Duncan Hotrail in it when it had the ret tortishell pickguard on it.  It did not get the JB until the pickguard was swapped with a white pearloid one.

Roseland was a JB Jr. then changed to a black full size JB with a white guard. This guitar also had a Nashville style TOM bridge on it, as opposed to the ABR style that wast used on the Sonic Blue Mustangs, and Jagstang. Sky stang 1(Sonic Blue) white Jb, Sky Stang 2 and 3, black JB. All of the Mustangs and Jagstang had the vibrato springs removed, tailpiece reversed, and locked down to the bridge plate.
