The Electro-Harmonix Double Muff Distortion Pedal stuffs 2 classic transistor Muff Fuzz effects from '69 into one box to give you double the trouble! Using just one gives you a hint of milky distortion. Cascading the second lets you turn your milk into outrageously thick cream. The Double Muff pedal's simple 2-knob operation makes it easy to dial in the perfect level of fuzz.
