I’ve have a Boss ME50 a fuzz factory and I’ve just bought a new Digteck Wammy Pedel and love it BUT does any one know why when I connect it in line before the fuzz factory I pick up heavy radio interference when the FF is active. But when I connect it after the fuzz factory its fine dandy and silent?

Guitar-Fuzz Factory-Wammy-ME50-Amp - All OK
Guitar-Wammy-Fuzz Factory-ME50-Amp - I get radio Moscow when FF is switched in???
