Might be one for Enzo? A friend has one of these and he says when you activate the tremolo the amp's volume goes down. I told him thats the nature of a trem because tremolo is a variable volume thing. But he said no, it is lower even at the peak height of the volume and that it is a common issue among delta blues owners. I figured if theres a fix for this Enzo might know being a PV service tech. But if anyone knows please clue me in so i can mod this for him. Thanks
