This is a plus with a standard 9V power supply, it allows me to distribute food to my pedalboard 8 pedals. No negative comments, mode diode is nice, it's more fun. The pedals do not hum, it depends on the supply entered with a 9V 400mA power, I can distribute it on all of my pedals without snoring. With my loop pedal is a bit tight, it does not light up. With food, 1V, it's good. No complaints report
