I recently added my 8th pedal in my pedal board and that broke the noise barrier for me. I had been using an old boss tuner to power my board but 8 pedals were too many for the daisy chain cable. My pedal board sounded like an idling jet. I went to my local Sam Ash to get a power supply and they recommended the mxr iso brick. I ripped apart my PedalTrain board and put this in the bottom. An hour later I couldn't believe what I was hearing - absolutely nothing. Even w my amp cranked, zero pedal noise. I highly recommend this product.
