Nice to be reminded how Studio 2 looks like (I almost forgot!), but isn't it fascinating that after months and months of working on the most exciting thing – new MK songs! – all Guy has to share is a list of the gear they used. I can totally see how he's helpful in the studio, but he surely must be the most boring person on earth.
If you mean the big one, that's Studio 1. The Studio 2 is just a small room where MK goes to record guitar and vocals alone, and sometimes other instruments, but alone as it's too small to have more than one "big instrument" like keyboards, drums etc.
Studio2 is where Mk and Guy work when they are alone, usually MK inside the studio and Guy from the control room.
This is studio 1
