Wondering if anyone's found a solution to this: I have a bunch of pedals (Visual Sound, Boss, E-H) and got a Visual-Sound Multi-plug adapter so I could stop using batteries. Works fine for the Boss and VS pedals, but the E-H Big Muff has a different jack size, so I'm still running off 9v batteries. I don't want to get a separate power adapter for the Big Muff and wonder if anyone knows if there's a good converter I can stick on the VS Multiplug to make it fit the Big Muff, or even what the spec is for the Big Muff jack so I can search for one myself. Thoughts?
