Having tried to set something inspired by that up at my own place - amps and processors within arm’s reach, with just enough space to play the guitar and roll the chair around to mess with the controls - I couldn’t get comfortable.
It really was a little claustrophobic.
I kept banging the guitar into tables and gear, and there was no room for my other instruments (keyboards). Plus I had speaker wires running everywhere, and my pedalboard under foot and in the way when not needed. My conclusion was that his setup is exactly suited to his needs, but isn’t ergonomic for me.
As it is, my main controller keyboard is set up so I can get to it by turning my chair about 90 degrees, but there’s very little room when I play the guitar sitting at the workstation when recording. When I move the keyboard further out so that’s easier, I wind up having it too far away when I’m composing on keys.
I have a keyboard stand that was originally designed for my old place, where I had one of my main keyboards on the top surface, and a pull-out drawer for one of my smaller keyboards. My main controller was on a third stand, with rack spaces off to the left, and the setup more or less wrapped around me; however a lot more “moving around” space was designed into the floor plan, and my mixing console was at the other end.
Unfortunately, I’ve learned that to take advantage of the space in a particular room, something designed for a different room isn’t the greatest fit. The problem is that my furniture was built really, really well 20 years ago, and it’s still like new, looks great, etc., and I can’t bear to get rid of it.
