  • Quick question about amp hum/ground loops/daisy chain

    I'm powering my fx loop pedals as well as my pedals before the amp with the same power supply, causing a decent hum noise. If I kept the fx loop pedals daisy chained together, but powered the pedals in front of the amp with 9volt batteries would that eliminate this?

    I know I need to get a voodoo labs power supply but I need a way to fix it until I can pick one up

    Maybe. But even with using batteries in front, you still have two separate power supplies, and the ground loop could be there. Or you may not have a ground loop at all. Some pedals just refuse to play nice and create noise when daisy-chained, no matter what. I would start by removing *one* pedal at a time from your present set-up to determine if it is indeed an individual pedal causing the hum.

      Before i ran my delays and reverbs in my fx loop, and just ran everything through the front of the amp with all the same power supply i didnt get any hum at all. I'll try a few different things and see what works best
