I am using a Peavey Max 112 combo and an Ibanez soundgear 400 active bass, I get can tons of tone and love the sounds I get, but there is an interesting buzz. This buzz increases when I turn up the treble on the bass, but is not that prevalent if I turn bass treble "off" but the combo treble up higher (though when loud enough there is the to be expected noise).

What I found interesting about this buzz is that when my bass is turned at a certain angle to the amp (almost facing completely toward it or 180 degrees the opposite way) the buzz almost completely goes away. When then bass is any other angle to the amp the buzz is right there. Could this be magnetic?
