With a One Control Black Loop, you get two rock-solid switchable effects loops you can use to make your entire pedalboard much more flexible. This simple effects switcher lets you connect two completely independent guitar pedal effects loops, allowing you to instantly turn on and off entire multi-effects chains with the press of a single footswitch. Whether you"re switching a dozen pedals together or simply adding true-bypass switching to your permanently buffered effects boxes, you"ll get a ton of mileage out of the Black Loop. And when you run it off of a power supply, you also get two channels of 9V power distribution from your One Control Black Loop stompbox switcher.
