I've got the trem blocked with a piece of wood in the back, so all I need to do is maintain more tension in the strings than in the springs. That said, would anything go haywire if I just removed all the springs? I think they are resonating with the low E string causing the note to "warble".
I wouldn't do it, just loosen them. They are going to help with stability even when the trem is blocked off.
