I have my Axe Fx II hooked into a mesa power amp on output 1 and an MBox two on XLR output 2. I am experiencing a high pitched buzz on both channels. Does anyone know what could be causing this? Thanks
So which is it? Do you get a buzz when just the MBox input (which you say is your interface) is used and the Mesa unplugged, or not? You've contradicted yourself.The sound is the same if I unplug either one or have both plugged in. I don't seem to have the issue when I run an XLR into the XLR preamp on my interface, which I just discovered.
