I use a switchblade made by sound sculpture. 16 ins 16 outs. You can connect anything to anything else in any order you like. And then completely change it on the next preset and even morph two presets with an expression pedal.
Not cheap though. But it makes everything else I own much more useful. There is NO other unit before or since that can do what this will do. To duplicate it you'd need a switcher, router, and a mixer and still wouldn't be able to change effect order as easily.
Still in production and I've never seen one on Ebay. I guess the people who have them don't sell them.
