I have a Muff with tone wicker and a deluxe electric mistress both new. Both alone or with any of my other pedals work fine but when turned on together the volume quadruples. I have tried putting them in a different order nothing i have tried works. Whats the problem? In a related problem but not an EHX problem my Fuzz Face and Voodoo labs Wahzoo together have the same issue but not with any other pedal.
