Positive ground: Some pedals, such as the Nano Clone and Nano Muff OD have positive ground, instead of negative ground. They are normal polarity though. When daisy chained with pedals that are negative ground, they will not work properly. Pedals with positive ground must be on a separate power supply, or on a separate output of a power supply that has isolated outs.
Digital and analog pedals usually don’t daisy-chain well together. Digital pedals should either have their own power supply, or their own output on a power supply that has isolated outs.
Question: I’m tossing around the idea the idea of getting either a Muff OD or the Double Muff (leaning towards the latter). Do you know if the Double Muff has positive or negative ground? If it does have negative ground I’ll probably go with the DM as it’ll be one less power issue to worry about and it sounds a little more like an overdrive. And, while I’m at it, does anyone know if the DM even works well with a power supply? I’ve run into an anti-adapter trend with other EH stuff…
Thanks for the response. I suppose it’s possible that the guy I lent it too may have plugged it into a power supply with the wrong polarity although he didn’t seem like the kind of person who would make that mistake… If that is what happened do I need to order some new components?
