Hi! I have correctly plug my POD HD pro into my amp (an ibanez tone blaster) with the 4CM. When i use the POD's patch, everything work fine. But when i try to use my amp Overdrive sound, i hear it clean, but with an overdrive barely audible in the background. I have made a Null patch, no amp, no FX. I put a FX Loop. But i still can't hear my amp sound :( Anybody can help with that?
