Looking at some of those angled stereo cabinet in the past, such as Watkins Dominator or Gibson GA-79RVT, I want to make something like that. However, I am wondering: How effective are these stereo? Or are they about as stereo as the many "stereo" 2x12?

I may also instead adapt to the Danelectro Commando fold out configuration instead.
