Wow, 22 channels of 'faders'. I absolutely love the giant Frankenstein 'push the lever' faders. I've often wanted to make a desk that way.
I wouldn't be surprised if that became collector bait and was never used again, regardless of whether it's in working condition. The Dark Side console? That's historic importance. Ought to be in the Smithsonian.
That, or Dave Grohl can take to buying up all the great consoles of history :) heck, he got the one from Sound City, why not this?
