I didn't have a yard stick with me to measure, but got a pretty close up
view of his rig at the show. AFAIK those were 18's in separate Mesa Logo cabs.
They looked way too big for 15's. He also had his 2X10-1X15 combo cab, so the
scale of everything sure made those cabs look like 18's.
One of my friends has the EV Road Ready 1X18 that same size
so I'm thinking McCartney had them special ordered through Mesa.
If I'm wrong, then so be it.
