BTW...I usually use the headphone jack/aux in to practice but last night ran an XLR to a small board and used the headphone feed from that. I still plugged in a cable to the headphone jack on the amp to keep things quiet. There is some processing going on with the XLR...seems to narrow the dynamic range a bit and add color (since it is set for the FOH). I don't like it as much as the headphone out mix though. But putting a bass signal through subs requires a different tone. And the signal is certainly not sterile.
