It doesn't work according to the specification, which is even worse: The Wahmmy pedal requires 1300 mA, it is written on the pedal and on the plug that comes with it. It doesn't work with this joyo motyo, which in principle can handle 2000mA. The pedal tries to start, it flashes continuously because the voltage always drops, so it is practically unusable. I wanted to let go of the outlet with this thing, but now I'm tied to the same outlet, so I don't even use this shit, it just collects dust. If you still need a power outlet, I won't push this to the plus side.
