So whenever I use two amps in a patch on the HD500, I am unable to pan them hard left and right for true stereo sound. I have the inputs setup like this: Input 1, Guitar; Input 2, Same. Both channels in the mixer are set at 0db, which is default. The left channel, or amp "a", will pan all the way left like it should, but the right channel, amp "b", will not pan hard right like it should.
I remember when I first purchased the HD500 they would pan hard left and right just fine, but now they will not.
Does anyone know what I'm doing wrong?
