Hello! I've been having some problems with my pedals recently. I use a Boss OD 20 Multi Distortion Pedal, a Boss Super Overdrive Pedal and a Boss Mega Distortion, usually they all work fine but sometimes the power just cuts out on them. I know it's not the mains because it's happened at different venues and in the practice room, i've checked my leads and they're all fine as well. Sometimes when the pedals come back on a bright white light shines out of the back of the Boss OD 20 and the lights flicker on and off. I use a boss power adapter that connects to one of those extension wires that has 5 jacks on it so i can run multiple pedals off the one adapter. Has anyone any ideas as to why this might be happening?
