Jenny's playing guitar and Theresa's playing bass? I'm very confused right now. I wonder if Theresa has an endorsement deal with Fender that keeps her from using Jenny's Rickenbacker. I would love to see that. Not that there's anything wrong with using a P-Bass.
Nothing like that, this bass that Theresa is playing is her's and it's apperently very special to her because it was custom made by Stella's dad. She talks about it in the Warpaint Rig Rundown.
