the buzzing stays the same no matter where I stand. I've even tried cutting everything electrical off that's anywehre near where I play. I've also wiggled and jiggled all connections (on the outside) and nothing changes. I'm going to try moving it to another room and a different outlet. I've always kept it plugged into a very high quality serge protector, but I'll try without incase that might be part of the problem. Like I said before, you can hear it in all 3 channels, just the more gain, the louder it gets. Thanks for any help.
