If you ever get squealing feedback when you try to make a Direct Amp Profile.

If you ever get squealing feedback when you try to make a Direct Amp Profile, you may have the Direct Box too close to the amplifier’s input. I put a Proco DB1 direct box on top of my Marshall Jubilee head, and it squealed horribly as I turned up the amp. I moved the direct box away from the amp, and the squeal disappeared
