Hmz to be honest i dont exactly what i lose.I think i lose some gain.All i know is that the sound that s coming to my hears is weaker and muffled (as i u said) in comparison to the sound that s coming when a cabel is connected.The settings of my amp are they same when i plug in the wireless system.I just dont what s wrong.The sound with the cable is so warm, "full" and strong and when i connect the wireless then the soumd is weaker...muffled.Like something blocks a part of the sound from my guitar coming to my amp.
