thanks unix-guy, it's appreciated. I think the isssue though is that the entire signal is going out via USB and returning via USB. When it returns to the Axe via USB to be monitored there is a loss of level, it's just lower after it comes back in. So USB levels are great into / out Ableton, and Ableton is not attenuating level. It seems like the Axe is lowering the USB level on returns in. This is seen in the metering on the Axe Output 3/4. Every attempt to use the Axe to attenuate USB doesn't seem to fix the problem but I am probably missing something in the Axe
