So, I just bought a Big Muff a few months ago, and it’s having problems, but I think it’s cause of my power supply stuff.

I’m powering it using my SKB Pedal board ps-45. I’m not using a power supply directly to it. Instead, I grabbed a stereo mini male to stereo mini male plug and powered it from the 9v bunch on the top of it.

I’m guessing I did the wrong thing, because randomly the volume will drop and everything will buzz and scratch if I try to take it out of the pedal chain. The problem is it doesn’t do this everywhere, and it just does it on occasion. In different bedroom locations, it works just fine. Do I need to buy the actual power supply, or did I get a bad pedal, or does this pedal not react well to voltage situations where lots of things are plugged in (I mean a pedal board and amp on the same electrical circuit in the same wall outlet at gigs?)
