I'm getting some feedback when I turn my amp up past a certain volume. I'm not sure what's causing it, so here's my rig. Maybe someone can help me out.

'72 Telecaster Reissue
v
Digitech GSP1101 Rackmount Preamp
v
BBE Sonic Maximizer
v
Orange Tiny Terror Head
v
Orange PC212 Cab


Any ideas would be greatly appreciated. Thanks!!

that could be it. it's doing it whether I'm facing the amp or not. would it still cause feedback if the pickups are facing the other direction?
