On the black pickup on the Sonic Blue one. The back up to the main In Utero tour Mustang had the black JB. He 2 Sonic Blue Mustangs on tour with HBs. The main one was the one with the white one in it, which is on display in Seattle. The one with the black HB is on display at the Rock N Roll Hall of Fame.
Yea we know that, but the one hes famous for using is the one with the white JB. All it comes down to is to save money in production and use one single one for all 3 guitars instead of using the right ones. For instance the competition mustang should have a hotrail, not a full sized JB, but its cheaper to cut all the bodies the same, cut all the pickguards the same and use the same pickups in them all.
