Hi,
So I've searched through the threads but didn't find any discussions that specifically answered the question I have. I'm using the POD HD400 and have a patch with a distortion effect on FX1 and a delay effect on FX3. I've run into instances in a live setting where I only have the FX1 effect activated, I literally am muting the guitar strings, have the volume pedal in the up position, then I stomp on FX3 to prepare for using it later and a note will squeal through the house. I have a MIM Fender Strat plugged into the POD HD400 then going into a Fender Hot Rod Deville tube amp. I'm connecting the POD HD400 with the 4 cable method. I just can't understand how sound comes through when I have the volume pedal up. I thought that's the reason for the volume pedal, to prevent any sound. If someone can help me figure this out, I would be thankful. It's caused me some embarrassing experiences when it's silent and I'm just getting ready for another part in a song and then I'm squealing a note through the house unexpectedly. Thank you.
