In this interview/article, Stefanie talks about using a Gretsch USA Custom kit, both at home and in the studio.

Did you talk to Jesse about how you wanted the drums to sound?

“We let him know, ‘We’re going to rent a drum kit like Stefanie’s kit, it’s very important to us and to her that she knows how to tune it, we know the sound.’ When we picked up the rented drum kit, it felt like home. It’s a good thing we didn’t use a studio drum kit because you can hear I’m used to playing on this kit. We rented the same drum kit I have at home [a Gretsch USA Custom]. He suggested, ‘I have this Ludwig kit that’s amazing, and I have this DW kit’, but I was like no. It’s already stressful to go to the other end of the world to record with another crazy person like us, not knowing what to expect, not knowing how the songs are going to sound. Let’s rent our own gear and then we’ll see about the rest.”
