Yeah, the Visual Sound ones work perfectly. I thought maybe it had to do with the tip of the adapter, as the VS ones only have the actual plug being metal, and the GC ones have metal going back in a washer type thing to the back of the plug. But it shorts out before that washer part even hits the pedal. Just as I was thinking of getting some old DODs! I don't want to pay an extra $5 for every pedal just to get an adapter.Only thing I can think of is that the GC brand adapter is wired wrong, or it's got a short or open and it's messing up the rest of the chain.
I use the Visual Sound branded 1/8" adapters for my Rat and old DOD pedals and it's always worked fine.
