alright, so my friend gave me his Digitech PR50 pedal the other, i plugged it into my amp (some old 115 watt crate) alongside my Digitech grunge pedal. but when i do that there is some extreme buzzing, or humming comming from my amp. I use an epiphone les paul if that makes a difference

any tips on how to get rid of the buzzing?

i blame the fact you have a grunge pedal! i hate those...and the rp50 sucks, but i dont get any buzzing from mine...
