I've noticed that several of her basses, when she's playing while sitting, look that way.
But that sort of awkward/too big appearance goes away when she's playing while standing.
Maybe the Mayones is the same way?
Two things I noticed that were interesting: based on the pole positions in the pickups, it appears to be a double P configuration; the fret dots, in addition to having her name at the 12th, switch sides.
Low-end dots on the low side, high-end dots on the high side, instead of all just straight up the center.
