The Electro-Harmonix Signal Pad is a handy tool for knocking down the volume of your signal at the kick of a foot. Need to quickly come down in volume for a quiet section of a song? Stomp on the Signal Pad. Do you have a pedal you want to use that doesn't love the hot output of the pedal before it? Simply insert the EHX Signal Pad in between the two and passively attenuate the volume going into the second pedal.
