Looks like she's playing an acoustic Guild....
Cool video! Yes it's a Guild but I have difficulties about the model.
First thought about a GAD-30 due to the shiny headstock inlays, but has a normal pickguard and a "white" TRC (upside down however!). While the TRC could be fake and the pickguard changed, somehow also two very large "dots" are on a normal shaped Guild bridge and the "dots" on the fingerboard are also extra big as far as I can see in above picture.
It's not her guitar at the end I believe... Here is a picture close up from April 2019. It seems to be owned by her partner Huw Evans (a.k.a. H. Hawkline), who was also playing the guitar below. Due to the headstock inlay and truss rod cover and wooden (?) pickguard to me that looks like a Nashville custom shop guitar. Mahogany back and sides. Can't really see what the two inlays on the bridge are.
That's a good guess on my side and I'm sure Hans will correct me.
