Hello everyone. I have a question: I recently powered-up my pedals with my trusty 1-spot. However, I noticed that I get a loud hum when all pedals are powered by the daisy chain. I thought it was my bass, but I get the same hum with all my basses, including my Roscoe which was recently worked on and shielded by Keith Roscoe himself. It also happens no matter which wall or building I plug into. So it might not be a ground loop or something in the walls. To isolate the issue I did the following: 1. Ran and powered only my GK Plex with the 1-spot with and without the daisy chain connection --> no hum; 2. Powered the GK Plex with the 1-spot daisy chain and ran it into my Zoom B1on, but with the Zoom running on battery power only --> no hum; 3. Powered both the GK Plex and the Zoom with the 1-spot daisy chain --> loud hum Therefore, the hum occurs when all pedals are powered by the 1-spot daisy chain. How do I eliminate the hum?
