Here's DJ Ramsey, from Scottsdale, Arizona, doing a pretty good job of scratching on two tape decks and a mixer. You may remember Russian DJ Artyom doing the same thing with a custom rig in 2005, and Japanese experimenter-in-chief Tucker (he of the hot ribbon controller action) has also had a go. (Thanks, Chris)

I sent you a Youtube link of a DJ in the late 80s/early 90s using two reel to reels at a competition but can't find it now to post in response.
