Why does my Digitech Grunge pedal have so much feedback and a loud noise when im not playing?

Question

This is my first pedal, i dunno wat a clean channel is or distortion channel...

Answer 1

do you have it on the distorted channel?  always play a distortion pedal on the clean channel, overdrive pedals can go on eitehr.  try turnign down the gain, otherwise you might just have a S****y amp or connection

Answer 2
