The H9 is the largest current draw, but I only have 4 other pedals, where one of them draws 250mA and the others draw <100mA, and my power supply is rated for 1.7A. Also, I should note that the frequency of the hum changes when the text on the H9’s LCD screen changes, almost like it’s playing a melody.
