Hey Larry! I am having the exact same issue, but my guitar pickups are passive. I'm using a 1990 Ibanez RG570 with a Dimarzio DP100 Super Distort in bridge and a Dimarzio DP193 Air Norton in the Neck with the stock middle single coil. I'm plugged straight into the Input 1 of my USB96. I have turned both inputs all the way down on my USB96 and when I barely strum it doesn't clip. When I palm/mute and strum hard, instant clipping. That seems very stupid on a device of this type. When I turn a pot all the way off, nothing should get through. What's up Presonus? What are we doing wrong?
