Hey folks, maybe someone can help me troubleshoot this. It's actually been doing this for a long time, but I have two of them so this pedal has just been sitting on a shelf. Like the thread title says, it's rather noisy in the effects loop and makes intermittent loud "pop" noises as I play, which is exacerbated by high gain. The tone itself is identical to my other 10-band, when dialed the same. I'd like to get it working so I can sell one of them. Things I've tried: Cleaned input and output ports with de-oxit. Removed the pcb from the housing and sprayed de-oxit into all the sliders and worked them up and down a few times each. Tried a different DC adapter (from the other EQ pedal, but both are the appropriate 18-volt adapters). I also tried different wall outlets. None of these attempts changed anything. Any other ideas?
