So i have all my stuff hooked up and i'm getting crazy feedback,I try cutting the gain,same with treble,i'm turnin knobs on my axe and my head,and my dsp 16,check the pedal,unhook the wah,I'm going nuts,I walk away with guitar in hand about 7 feet away all feedback is gone,tone knob on my axe is loose so I tighten it it,still have feedback when I'm close,is this my pickups,which are duncan designs,or does this just happen with this equipment?
