I made myself a dual loop selector earlier this year. After some thought, and discovering just how many 3PDT and 4PDT toggles I had in my parts bin, I think I'm going to install an order-flipper switch in my loop selector, so that loop A can go before loop B or after it. And whatever goes into each loop, be it compressor, wah, fuzz, phaser, EQ, etc., can be free to modify something else, or BE modified by something else, with no requirement to be moved from it's location on a pedalboard, or repatched, in order to accomplish the flipping. I'm surprised that places like Road Rage haven't already started making order-flipping a feature in their loop-selectors. Doesn't have to be applicable to every loop in the unit, but as long as there are two or more loops to select from, and toggled order-flipping for two of those loops, you're in good shape.
